mdadm: re-add mdadm-ptest to PTESTS_SLOW

The ptest problems reported in e21021dc00ec ("mdadm: drop from PTESTS_SLOW")
should now be fixed, so mdadm can be added back to PTESTS_SLOW (a qemux86-64
test run takes about ~12 minutes to execute with kvm).

For the testcases to run correctly, there must be enough rootfs space to create
13 loop devices. Similar to strace and lttng-tools, add a new
IMAGE_ROOTFS_EXTRA_SPACE entry for mdadm-ptest.
