lvm2: libdevicemapper package needs udev rules and dmsetup

Browse Source 
Applications like kpartx and cryptsetup were broken by moving only
libdevicemapper itself into a separate package: as a result of that
change, lvm2 was not getting pulled into images anymore although
libdevicemapper depends on dmsetup and udev rules to be fully
functional.

For example, "kpartx -as" started to hang while waiting for the udev
rules to trigger, which is what creates the /dev/mapper/ entries for
the new partitions (see also
https://github.com/docker/docker/issues/22025#issuecomment-243943728).

Putting udev rules and dmsetup also into libdevicemapper is perhaps
counter-intuitive, but necessary to keep the package functioning. A
full lvm2 installation is guaranteed to pull them in, too, both
because of implicit library dependencies and (just to be sure) an
explicit RDEPENDS.

lvm2-native doesn't have packages, so this RDEPENDS must be limited to
the target case.
