btrfs-progs: tests: add execution permission and warning messages

Running test misc/056 results in no output, because the script lacked
execution permissions. To prevent this to accidentally happen:

- fix permissions in misc-tests/056-subvolume-list-uuid/test.sh
- add warning message if test.sh without execution permission in the
  test driver scripts, the exception are fuzz-tests where not all
  directories contain the test.sh
