Avoid private libs explore in public

The spec automaticlly provides the libpq.so which is the same with postgresql-libs package.

In public area, it should not find 2 or more packages provide the same lib.

So this might break the downstream dependencies which using pkgconfig(libpq).
For this reason, we hide the gpdb private libs.
