Re-testing gitlab CI shows the x86-64 TCG tests take ~100s each, are
the longest-running tests. They are close to the ~150s taken by the
disabled ppc64 and s390x tests. From avocado-system-centos:

  boot_linux.py:BootLinuxX8664.test_pc_i440fx_tcg:  PASS (112.34 s)
  boot_linux.py:BootLinuxX8664.test_pc_q35_tcg:  PASS (97.05 s)
  boot_linux.py:BootLinuxPPC64.test_pseries_tcg:  PASS (148.86 s)
  boot_linux.py:BootLinuxS390X.test_s390_ccw_virtio_tcg:  PASS (149.83 s)

So disable the x86-64 tests as well.

The other way we could go is enabling them all since ppc64 and s390s are
now much faster than when they were originally disabled; or to only
enable q35, giving at least one boot_linux.py test.

Thanks,
