Looks good to me overall, tested with 4.10-rc5 kernel with and without
the proposed kernel fix, results are all as expected. Some minor issues
inline.

Better to add new test with mode 755, otherwise git diff shows mode
changes after tests being run.

Please avoid using "run_check" (called by _run_btrfs_util_prog) if
possible. We can use $BTRFS_UTIL_PROG directly and throw away stdout or
append it to $seqres.full, and stderr from these commands will break the
golden image.
