redhat/configs: create a separate config for gcov options

Use existing config infrastructure to build and validate gcov-enabled configs. Meaning for each arch we also apply GCOV options on top and validate it.

From same options dir (kgcov) build also partial config, which contains only GCOV options. We can merge this partial config during build on top of existing config, which avoids the need to store all possible combinations in dist-git and SRPM.
