Btrfs-progs: add make test framework

We need to start adding some sanity tests to btrfs-progs to make sure we aren't
breaking things with our patches.  The most important of these tools is btrfsck.
This patch gets things started by adding a basic btrfsck test that makes sure we
can fix a corruption problem we know we can fix.  Thanks,
