kvm/x86: Move MSR_IA32_ARCH_CAPABILITIES to array emulated_msrs

Xiaoyao Li · bonzini · commit 2bdb76c015df · 2019-03-28T17:29:01.000+01:00
Since MSR_IA32_ARCH_CAPABILITIES is emualted unconditionally even if
host doesn't suppot it. We should move it to array emulated_msrs from
arry msrs_to_save, to report to userspace that guest support this msr.
