btrfs: test xattr changes for RO btrfs property
Test creation, modification and deletion of xattr for a BTRFS filesystem
which has the read-only property set to true.
Re-test the same after read-only property is set to false.
This tests the bug for "security.*" modifications which escape
xattr_permission(), because security parameters are usually let through
in xattr_permission, without checking
inode_permission()->btrfs_permission().
This resulted in being able to change a security xattr on a RO subvolume
until it got fixed by kernel commit b51111271b03 ("btrfs: check if root
is readonly while setting security xattr").
