Service files to remove orphaned UBI volumes

This commit provides supplementary service files for
openbmc/openbmc#2264, which adds a function to delete all versions to
each of the BMC and host updaters.

The service files introduced in this change will locate any "orphaned"
BMC or host volumes - that is to say, volumes which do not correspond to
a current version on the system.
