selftests/resctrl: Fix non-contiguous CBM check for Hygon

The resctrl selftest currently fails on Hygon CPUs that always supports
non-contiguous CBM, printing the error:

  "# Hardware and kernel differ on non-contiguous CBM support!"

This occurs because the arch_supports_noncont_cat() function lacks
vendor detection for Hygon CPUs, preventing proper identification of
their non-contiguous CBM capability.

Fix this by adding Hygon vendor ID detection to
arch_supports_noncont_cat().
