Changes from v1:
* Added some prints printing what is being tested
* The test now uses the _btrfs_get_subvolid to get subvolumeids instead of using
  plain integers

The usa of _run_btrfs_util_prog is deprecated, please use bare
$BTRFS_UTIL_PROG commands, and do filter as needed.

Use $AWK_PROG instead of bare awk. And I noticed this pattern repeated
for several times, make it a local helper function?

Does _scratch_unmount work here?
