clonerange: test remapping the rainbow

Add some more clone range tests that missed various "wacky" combinations
of file state.  Specifically, we test reflinking into and out of rainbow
ranges (a mix of real, unwritten, hole, delalloc, and shared extents),
and also we test that we can correctly handle double-inode locking no
matter what order of inodes or the filesystem's locking rules.
