mdadm: skip running 04update-uuid and 07revert-inplace testcases

04update-uuid and 07revert-inplace tests are unreliable and fail intermittently
on the autobuilder (BZ#15181 and BZ#15159). Unfortunately, the failures cannot
be reproduced locally and the logs cannot be retrieved from the AB.

Mark the testcases as BROKEN to skip them when running ptest.
