On old distros, we can't detect some btrfs structs because of undeclared 'NULL' in
btrfs_err_str function. This function has been removed after kernel
commit 68598d2ea8863 ("btrfs: remove btrfs_err_str function from uapi/linux/btrfs.h").
Fix this bug in xfstests layer by adding stddef.h because NULL is defined in stddef.h(it is
in /usr/lib/gcc*/ directory).
