Subject: Drop go-rpm-macros for RHEL


As go-rpm-macros are still not part of RHEL Buildroot, let's add the
conditional and only use it on Fedora.

This change requires:
- explicitly setting "_find_debuginfo_dwz_opts" and
  "_dwz_low_mem_die_limit", for generating the debug packages when not
  using go-rpm-macros;

- explicitly define gobuild, in case its not defined;
  - The definition was taken from Fedora 33 podman.spec and tested on
    RHEL 8.2;

- depend on golang instead of go-rpm-macros when building on RHEL;

- depend on compiler(go-compiler), in order to have debugsource and
  debuginfo packages generated, when building on RHEL.
