xfstests: move remaining tests out of top level directory

These are tests that are shared between multiple filesystems (moved
to shared), and udf/btrfs/ext4 specific tests, moved to appropriate
directories.

I created the "shared" directory to indicate tests that are not
truly generic, but also not filesystem specific. They might rely on
a feature that is only implmented in a few filesystems and so can't
be truly generic.
