[skip-ci] TMT: system tests

This commit adds TMT jobs for system tests triggered via Packit for
all active Fedora and CentOS Stream releases on x86_64.

TODO: enable aarch64 tests.

Official Fedora and CentOS Stream spec and gating test configs can be
synced from upstream by Packit, effectively upstreaming almost all
mainteenance.
