Put the resources_dir flag into its own target.

I had to change approach. Unfortunately we can't expect
that test_main_lib users link with fileutils, which causes it to
not link when the override symbol is missing.

New approach: resources_dir_flag is now a separate target, it
will be depended upon by the downstream override, which just
reads the flag and returns it as the resource dir. This gets
rid of the mutable state downstream as well.

So:
1) Land this
2) Make downstream read the flag instead of keeping its own state
3) Remove OverrideResourcesDir upstream and clean up the hacks
4) Remove the now orphaned OverrideResourcesDir downstream
