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.

-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS

-git-remote-persistent-https
-
-The git-remote-persistent-https binary speeds up SSL operations
-by running a daemon job (git-remote-persistent-https--proxy) that
-keeps a connection open to a server.
-
-
-PRE-BUILT BINARIES
-
-Darwin amd64:
-https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
-
-Linux amd64:
-https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
-
-
-INSTALLING
-
-Move all of the git-remote-persistent-http* binaries to a directory
-in PATH.
-
-
-USAGE
-
-HTTPS requests can be delegated to the proxy by using the
-"persistent-https" scheme, e.g.
-
-git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
-
-Likewise, .gitconfig can be updated as follows to rewrite https urls
-to use persistent-https:
-
-[url "persistent-https"]
-	insteadof = https
-[url "persistent-http"]
-	insteadof = http
-
-You may also want to allow the use of the persistent-https helper for
-submodule URLs (since any https URLs pointing to submodules will be
-rewritten, and Git's out-of-the-box defaults forbid submodules from
-using unknown remote helpers):
-
-[protocol "persistent-https"]
-	allow = always
-[protocol "persistent-http"]
-	allow = always
-
-
-#####################################################################
-# BUILDING FROM SOURCE
-#####################################################################
-
-LOCATION
-
-The source is available in the contrib/persistent-https directory of
-the Git source repository. The Git source repository is available at
-git://git.kernel.org/pub/scm/git/git.git/
-https://kernel.googlesource.com/pub/scm/git/git
-
-
-PREREQUISITES
-
-The code is written in Go (http://golang.org/) and the Go compiler is
-required. Currently, the compiler must be built and installed from tip
-of source, in order to include a fix in the reverse http proxy:
-http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
-
-
-BUILDING
-
-Run "make" to build the binaries. See the section on
-INSTALLING above.
