In I008841988547573878c4e06e82f0fa55084e51b5 we started enabling a
bunch of libvirt enlightenments for Windows unconditionally. Turns
out, the `evmcs` enlightenment only works on Intel hosts, and we broke
the ability to run Windows guests on AMD machines. Until we become
smarter about conditionally enabling evmcs (with something like traits
for host CPU features), just stop enabling it at all.
