With image locking, opening /dev/null can fail when multiple tests run
in parallel (make -j2, for example). Use null-co:// as the null protocol
doesn't do image locking.
While it's arguable we could special-case /dev/null, /dev/zero,
/dev/urandom etc in raw-posix driver, it is not really necessary because
user can always specify lock-mode=off when it is appropriate. So let's
write sensible testing code too.
