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.

--git-ls-tree - Displays a tree object in human readable form
-+git-ls-tree - Lists the contents of a tree object.

- SYNOPSIS

--'git-ls-tree' [-r] [-z] <tree-ish> [paths...]
-+'git-ls-tree' [-d] [-r] [-z] <tree-ish> [paths...]
- 
- DESCRIPTION
- -----------
--Converts the tree object to a human readable (and script processable)
--form.
-+Lists the contents of a tree object, like what "/bin/ls -a" does
-+in the current working directory.
- 
- OPTIONS
- -------
- <tree-ish>::
- 	Id of a tree.
- 
-+-d::
-+	show only the named tree entry itself, not its children
-+
- -r::
- 	recurse into sub-trees
- 
-@@ -28,18 +31,19 @@ OPTIONS
- 	\0 line termination on output
- 
- paths::
--	Optionally, restrict the output of git-ls-tree to specific
--	paths. Directories will only list their tree blob ids.
--	Implies -r.
-+	When paths are given, shows them.  Otherwise implicitly
-+	uses the root level of the tree as the sole path argument.
-+
- 
- Output Format
- -------------

-+        <mode> SP <type> SP <object> TAB <file>
