Viosock driver's signature testing

[leidwang]

Support check viosock driver in virtio_driver_sign_check and win_sigverif.

ID: 4307, 4309

Summary by CodeRabbit

• New Features
  • Added support for the viosock virtio driver in driver signing checks and Windows signature verification tests.
  • Introduced version constraints for virtio-win (pre-WHQL and WHQL ranges) for the new viosock variant.
  • Updated host compatibility to exclude older RHEL host versions for these variants.

Walkthrough

Adds new with_viosock variant blocks to two test config files: qemu/tests/cfg/virtio_driver_sign_check.cfg and qemu/tests/cfg/win_sigverif.cfg. Both variants add host exclusions (no Host_RHEL.m6, Host_RHEL.m7, Host_RHEL.m8) and version constraints (required_virtio_win_prewhql = [0.1.291, ) and required_virtio_win = [1.9.48.0, )). The virtio_driver_sign_check variant registers the driver as "viosock". The win_sigverif variant sets driver_name="viosock", driver_verifier="VirtioSocket", and device_name="VirtIO Socket Driver".

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Homogeneous, small additions to two config files following existing patterns.
• No code logic changes, only configuration metadata.

Files/areas to check:

• Consistency of version constraints ([0.1.291, ) and [1.9.48.0, )) across both files.
• Exact strings: driver_name, driver_verifier, and device_name.
• Correctness and intended scope of Host_RHEL.m6/m7/m8 exclusions.
