Update fc.qemu to include fixes for AMD/Intel SSBD flag compatibility
Changelog
- Update fc.qemu to respect vendor-specific (AMD/Intel) bug flags and avoid illegal live migration and KVM host selection scenarios that result in immediate VM crashes. (PL-129769)
Security requirements:
- ensure availability
Tests
- manual tests to understand flag behaviour with specific qemu on AMD and Intel hosts
- extended automated coverage to include verification that we now avoid "cross contamination" of vendor specific flags
Fixes PL-129769
Closes PL-129769
