fedora.spec: exclude pcp-zeroconf files from base package
fedora.spec: exclude pcp-zeroconf files from base package

The pmlogconf/zeroconf config files were in the base package as
well as pcp-zeroconf, but should only be in the latter.

Fixes RHBZ#1456262. This would need to be separately pushed as
a spec update. The change here is just the copy in the PCP tree
(build/rpm/fedora.spec).
