Release notes: https://github.com/libgit2/libgit2/releases/tag/v0.27.0

This version solves a significant performance issue with generating
large diffs: https://github.com/libgit2/libgit2/issues/4460

While it seems a little sketchy to use Timecop in this way, this seems like
an exception can be made for test fixtures.
