[oe] [meta-networking][PATCH 1/2] dlm: Build fence only when pacemaker recipe is available

[Khem Raj]

pacemaker is not in meta-networking, and therefore dlm fails
to build when meta-cgl is not included, this changeset makes
the pacemaker dependency to be optional, and disabled by default
so users who have pacemaker in the bbfiles should enable pacemaker
support via a bbappend or setting it in config metadata
