contrib/rpm: skip tests for -Q build option

Previously, the --quick option only mattered when creating
the source tarball, to run `make dist` instead of the slower
`make distcheck`.

Extend its meaning to also skip unit tests while building the RPM.
You still can enable them with

  $ ./contrib/fedora/rpm/build_clean.sh -Q -w test

(cherry picked from commit c528a89519)
