[OS-BUILD PATCH 0/4] redhat/configs: rework platform keys loading

From: Bruno Meneguele on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1127 This MR enable specific platform keys to be loaded in the integrity platform keyring (`.platform`). In the current state of the kernel the three arches: x86_64, aarch64, s390x, ppc, have the ability to pass their platform (from UEFI, IPL or PPC secur boot) enrolled keys to the system. With that, I've enabled the INTEGRITY_PLATFORM_KEYRING to the four platforms in both RHEL and Fedora and also their respective LOAD_*_KEYS. With that, we are closer to upstream and also allow all platforms to evolve equaly during the next RHEL major release with Fedora users feedback. 56eef9231260 (Bruno Meneguele) redhat: load specific ARCH keys to INTEGRITY_PLATFORM_KEYRING 66ed9a2826ba (Bruno Meneguele) redhat: enable INTEGRITY_TRUSTED_KEYRING across all variants b66b54c92054 (Bruno Meneguele) redhat: enable SYSTEM_BLACKLIST_KEYRING across all variants 9a75ca99c03e (Bruno Meneguele) redhat: enable INTEGRITY_ASYMMETRIC_KEYS across all variants
