chore(3p/git): Unvendor git and track patches instead r/2903

This was vendored a long time ago under the expectation that keeping
it in sync with cgit would be easier this way, but it has proven not
to be a big issue.

On the other hand, a vendored copy of git is an annoying maintenance
burden. It is much easier to rebase the single (dottime) patch that we
have.

This removes the vendored copy of git and instead passes the git
source code to cgit via `pkgs.srcOnly`, which includes the applied
patch so that cgit can continue rendering dottime.

-The Steps to Build Git with VS2015 or VS2017 from the command line.
-
-1. Install the "vcpkg" open source package manager and build essential
-   third-party libraries.  The steps for this have been captured in a
-   set of convenience scripts.  These can be run from a stock Command
-   Prompt or from an SDK bash window:
-
-   $ cd <repo_root>
-   $ ./compat/vcbuild/vcpkg_install.bat
-
-   The vcpkg tools and all of the third-party sources will be installed
-   in this folder:
-      <repo_root>/compat/vcbuild/vcpkg/
-
-   A file will be created with a set of Makefile macros pointing to a
-   unified "include", "lib", and "bin" directory (release and debug) for
-   all of the required packages.  This file will be included by the main
-   Makefile:
-      <repo_root>/compat/vcbuild/MSVC-DEFS-GEN
-
-2. OPTIONALLY copy the third-party *.dll and *.pdb files into the repo
-   root to make it easier to run and debug git.exe without having to
-   manipulate your PATH.  This is especially true for debug sessions in
-   Visual Studio.
-
-   Use ONE of the following forms which should match how you want to
-   compile git.exe.
-
-   $ ./compat/vcbuild/vcpkg_copy_dlls.bat debug
-   $ ./compat/vcbuild/vcpkg_copy_dlls.bat release
-
-3. Build git using MSVC from an SDK bash window using one of the
-   following commands:
-
-   $ make MSVC=1
-   $ make MSVC=1 DEBUG=1
-
-================================================================
-
-Alternatively, run `make vcxproj` and then load the generated `git.sln` in
-Visual Studio. The initial build will install the vcpkg system and build the
-dependencies automatically. This will take a while.
-
-Instead of generating the `git.sln` file yourself (which requires a full Git
-for Windows SDK), you may want to consider fetching the `vs/master` branch of
-https://github.com/git-for-windows/git instead (which is updated automatically
-via CI running `make vcxproj`). The `vs/master` branch does not require a Git
-for Windows to build, but you can run the test scripts in a regular Git Bash.
-
-Note that `make vcxproj` will automatically add and commit the generated `.sln`
-and `.vcxproj` files to the repo. This is necessary to allow building a
-fully-testable Git in Visual Studio, where a regular Git Bash can be used to
-run the test scripts (as opposed to a full Git for Windows SDK): a number of
-build targets, such as Git commands implemented as Unix shell scripts (where
-`@@SHELL_PATH@@` and other placeholders are interpolated) require a full-blown
-Git for Windows SDK (which is about 10x the size of a regular Git for Windows
-installation).
-
-If your plan is to open a Pull Request with Git for Windows, it is a good idea
-to drop this commit before submitting.
-
-================================================================
-The Steps of Build Git with VS2008
-
-1. You need the build environment, which contains the Git dependencies
-   to be able to compile, link and run Git with MSVC.
-
-   You can either use the binary repository:
-
-       WWW: http://repo.or.cz/w/msvcgit.git
-       Git: git clone git://repo.or.cz/msvcgit.git
-       Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
-
-   and call the setup_32bit_env.cmd batch script before compiling Git,
-   (see repo/package README for details), or the source repository:
-
-       WWW: http://repo.or.cz/w/gitbuild.git
-       Git: git clone git://repo.or.cz/gitbuild.git
-       Zip: (None, as it's a project with submodules)
-
-   and build the support libs as instructed in that repo/package.
-
-2. Ensure you have the msysgit environment in your path, so you have
-   GNU Make, bash and perl available.
-
-       WWW: http://repo.or.cz/w/msysgit.git
-       Git: git clone git://repo.or.cz/msysgit.git
-       Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
-
-   This environment is also needed when you use the resulting
-   executables, since Git might need to run scripts which are part of
-   the git operations.
-
-3. Inside Git's directory run the command:
-       make command-list.h config-list.h
-   to generate the header file needed to compile git.
-
-4. Then either build Git with the GNU Make Makefile in the Git projects
-   root
-       make MSVC=1
-   or generate Visual Studio solution/projects (.sln/.vcproj) with the
-   command
-       perl contrib/buildsystems/generate -g Vcproj
-   and open and build the solution with the IDE
-       devenv git.sln /useenv
-   or build with the IDE build engine directly from the command line
-       devenv git.sln /useenv /build "Release|Win32"
-   The /useenv option is required, so Visual Studio picks up the
-   environment variables for the support libraries required to build
-   Git, which you set up in step 1.
-
-Done!

-@ECHO OFF
-REM ================================================================
-REM You can use either GCC (the default) or MSVC to build git
-REM using the GIT-SDK command line tools.
-REM        $ make
-REM        $ make MSVC=1
-REM
-REM GIT-SDK BASH windows inherit environment variables with all of
-REM the bin/lib/include paths for GCC.  It DOES NOT inherit values
-REM for the corresponding MSVC tools.
-REM
-REM During normal (non-git) Windows development, you launch one
-REM of the provided "developer command prompts" to set environment
-REM variables for the MSVC tools.
-REM
-REM Therefore, to allow MSVC command line builds of git from BASH
-REM and MAKE, we must blend these two different worlds.  This script
-REM attempts to do that.
-REM ================================================================
-REM This BAT file starts in a plain (non-developer) command prompt,
-REM searches for the "best" command prompt setup script, installs
-REM it into the current CMD process, and exports the various MSVC
-REM environment variables for use by MAKE.
-REM
-REM The output of this script should be written to a make "include
-REM file" and referenced by the top-level Makefile.
-REM
-REM See "config.mak.uname" (look for compat/vcbuild/MSVC-DEFS-GEN).
-REM ================================================================
-REM The provided command prompts are custom to each VS release and
-REM filled with lots of internal knowledge (such as Registry settings);
-REM even their names vary by release, so it is not appropriate for us
-REM to look inside them.  Rather, just run them in a subordinate
-REM process and extract the settings we need.
-REM ================================================================
-REM
-REM Current (VS2017 and beyond)
-REM -------------------
-REM Visual Studio 2017 introduced a new installation layout and
-REM support for side-by-side installation of multiple versions of
-REM VS2017.  Furthermore, these can all coexist with installations
-REM of previous versions of VS (which have a completely different
-REM layout on disk).
-REM
-REM VS2017 Update 2 introduced a "vswhere.exe" command:
-REM https://github.com/Microsoft/vswhere
-REM https://blogs.msdn.microsoft.com/heaths/2017/02/25/vswhere-available/
