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.

-# Parse event stream and convert individual events into a summary
-# record for the process.
-#
-# Git.exe generates one or more "event" records for each API method,
-# such as "start <argv>" and "exit <code>", during the life of the git
-# process.  Additionally, the input may contain interleaved events
-# from multiple concurrent git processes and/or multiple threads from
-# within a git process.
-#
-# Accumulate events for each process (based on its unique SID) in a
-# dictionary and emit process summary records.
-#
-# Convert some of the variable fields (such as elapsed time) into
-# placeholders (or omit them) to make HEREDOC comparisons easier in
-# the test scripts.
-#
-# We may also omit fields not (currently) useful for testing purposes.
