Rework weak modules logic

- Fix variable check when determining if NO_WEAK_MODULES is set.
- kABI is available only on SUSE and RHEL platforms, so avoid setting parameters
  for all other distributions.
- For SUSE, use the new script provided in suse-module-tools and not the
  one provided by suse-module-tools-legacy.
