mdadm: also install mdmon

This commit adjusts the mdadm package to also install the mdmon
utility, which is used to "monitor MD external metadata arrays". It
adds ~250 KB to the installed size:

-rwxr-xr-x 1 thomas thomas 446064 Oct 14 21:55 mdadm
-rwxr-xr-x 1 thomas thomas 244672 Oct 14 21:55 mdmon

Fixes bug #11376.
