[PATCH 1/2] util: Move virIsDevMapperDevice() to virdevmapper.c

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

When introducing virdevmapper.c (in v4.3.0-rc1~427) I didn't
realize there is a function that calls in devmapper. The function
is called virIsDevMapperDevice() and lives in virutil.c. Now that
we have a special file for handling devmapper move it there.
