[PATCH 6/9] inbox: inline and eliminate git_cleanup

[Eric Wong]

It was probably incorrect to use from max_git_epoch, and it's
small enough to inline into do_cleanup.  We'll also eliminate
the unnecessary deletion of {-altid_map} while we're in the
area, since we no longer cache/memoize that.

Fixes: 7e5cea05f061e757 ("inbox: rewrite cleanup to be more aggressive")
