selftests/resctrl: Add CPU vendor detection for Hygon
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.
