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.

-Error reporting in git
-======================
-
-`die`, `usage`, `error`, and `warning` report errors of various
-kinds.
-
-- `die` is for fatal application errors.  It prints a message to
-  the user and exits with status 128.
-
-- `usage` is for errors in command line usage.  After printing its
-  message, it exits with status 129.  (See also `usage_with_options`
-  in the link:api-parse-options.html[parse-options API].)
-
-- `error` is for non-fatal library errors.  It prints a message
-  to the user and returns -1 for convenience in signaling the error
-  to the caller.
-
-- `warning` is for reporting situations that probably should not
-  occur but which the user (and Git) can continue to work around
-  without running into too many problems.  Like `error`, it
-  returns -1 after reporting the situation to the caller.
-
-Customizable error handlers
----------------------------
-
-The default behavior of `die` and `error` is to write a message to
-stderr and then exit or return as appropriate.  This behavior can be
-overridden using `set_die_routine` and `set_error_routine`.  For
-example, "git daemon" uses set_die_routine to write the reason `die`
-was called to syslog before exiting.
-
-Library errors
---------------
-
-Functions return a negative integer on error.  Details beyond that
-vary from function to function:
-
-- Some functions return -1 for all errors.  Others return a more
-  specific value depending on how the caller might want to react
-  to the error.
-
-- Some functions report the error to stderr with `error`,
-  while others leave that for the caller to do.
-
-- errno is not meaningful on return from most functions (except
-  for thin wrappers for system calls).
-
-Check the function's API documentation to be sure.
-
-Caller-handled errors
----------------------
-
-An increasing number of functions take a parameter 'struct strbuf *err'.
-On error, such functions append a message about what went wrong to the
-'err' strbuf.  The message is meant to be complete enough to be passed
-to `die` or `error` as-is.  For example:
-
-	if (ref_transaction_commit(transaction, &err))
-		die("%s", err.buf);
-
-The 'err' parameter will be untouched if no error occurred, so multiple
-function calls can be chained:
-
-	t = ref_transaction_begin(&err);
-	if (!t ||
-	    ref_transaction_update(t, "HEAD", ..., &err) ||
-	    ret_transaction_commit(t, &err))
-		die("%s", err.buf);
-
-The 'err' parameter must be a pointer to a valid strbuf.  To silence
-a message, pass a strbuf that is explicitly ignored:
-
-	if (thing_that_can_fail_in_an_ignorable_way(..., &err))
-		/* This failure is okay. */
-		strbuf_reset(&err);
