selftests/resctrl: Add CPU vendor detection for Hygon

Browse Source 
The resctrl selftest currently fails on Hygon CPUs that support Platform
QoS features, printing the error:

  "# Can not get vendor info..."

This occurs because vendor detection is missing for Hygon CPUs.

Fix this by extending the CPU vendor detection logic to include
Hygon's vendor ID.
