We should ideally provide '/bin/pg_config' in postgresql-server-devel, and
provide no pg_config binary in libpq package.  But most of the Fedora packages
that use pg_config actually only build against PG libraries (and
postgresql-server-devel isn't needed).  So.., to avoid the initial rush around
rhbz#1618698 change, rather provide pg_server_config binary, which int urn means
that we'll have to fix only a minimal set of packages which really build
PostgreSQL server modules.
