x86: Implement standard hypervisor detection protocol

This provides cpuid-based Jailhouse detection conforming to the protocol
also used by other major hypervisors: set bit 31 of ecx for function
0x01, provide a signature via function 0x40000000 and a so far empty
feature set via function 0x40000001.
