build-system: change the logic when to build what

Specifically, don't conflate needing libgit2 with the Mac -builddep
argument, and when determining if we need to build libgit2 on Linux,
make sure to also check for a version that we may have built in a
previous run of the build.sh script.

This commit is much easier to understand with
  git show -w
as it contains quite a bit of simple indentation change.
