main: Add --link-checkout-speedup option to commit

And disable devino scan by default.  For the gnome-ostree build case,
our commits are from "make install DESTDIR=", so they won't be
hardlinks into the repo.  In that case, particularly as the repository
size grows, the cost of building up the devino -> checksum mapping
becomes a problem.

The compose step will use this option though.
