Since Amazon Linux commit amazonlinux/linux/b2e92ab17e440a97c716b701ecd897eebca11ac0, KVM passes through bit 27 of the `MSR_IA32_ARCH_CAPABILITIES` MSR (0x10A) to the guest, to let them know whether the processor they're running on is affected by RFDS. According to Intel, only Atom processors are affected [[1]], and accordingly, for all instances in our CI this bit is reported to be 1. Thus, update the baselines.
