[PATCH] Makefile: mark git-maintenance as a builtin

We normally get the list of builtin commands by expanding BUILTIN_OBJS.
But for commands which are embedded inside another's source file (e.g.,
cmd_show() in builtin/log.c), the Makefile needs to be told explicitly
about them.

Since cmd_maintenance() is inside buitin/gc.c, it should be listed
explicitly in the BUILT_INS list in the Makefile. Not doing so isn't
_too_ tragic, as it simply means we will not make a git-maintenance
symlink in libexec/git-core. Since we encourage people to use the "git
foo" form, even in scripts which have put libexec into their PATH,
nobody seems to have noticed.

I don't really care that much. I just happened to notice there is a
git-maintenance pattern in .gitignore which will not ever trigger.

I could actually see an argument that this is not worth doing for new
commands. The dashed forms of the other commands have worked for a long
time, so losing them would be a regression. But since git-maintenance
would never have worked, presumably everybody who cares is using the
recommended "git maintenance" form already.

So I'm happy with that direction, too, but in that case we should
probably remove the .gitignore entry. :)
