Package SPEC file into Meson distribution file

Put final SPEC file in GIT repository directly to avoid having
to bump Meson version to use distribution script. To avoid
having incoherent version numbers check the versions from CI.
Remove 'c' as project language, project don't need to compile
any files.
Meson however needs C compiler even if is not used so add to package
requirements.
Update CI to build RPM from package directly.
