postgresql-test-rpm-macros subpackage

We used to provide the functionality under postgresql-devel
subpackage, but that one has already too much purposes (we build
against that both client tools and server modules, using that for
tests is too much).

Newly, the postgresql-server package is automatically added as
transitive dependency, so the typical fix for dependant packages
would be:

    - BuildRequires: postgresql-devel
    - BuildRequires: postgresql-server
    + BuildRequires: postgresql-test-rpm-macros

(when the package doesn't need header files from postgresql-devel)
