gc docs: note "gc --aggressive" in "fast-import"
Amend the "PACKFILE OPTIMIZATION" section in "fast-import" to explain
that simply running "git gc --aggressive" after a "fast-import" should
properly optimize the repository. This is simpler and more effective
than the existing "repack" advice (which I'm keeping as it helps
explain things) because it e.g. also packs the newly imported refs.
