ci: More fixes and tweaks

+ ubuntu
  + fix build by adding --disable-ruby
  + fix a test failure due to missing python libvirt import

+ fedora
  + use `--privileged` docker flag which also handles seccomp disable
    + this makes some network tests work, so enable them

  + exclude a flakey test
  + better document remaining disabled tests
