perf: Fix hypervisor sample reporting
cpumode bits are defined as such:
#define PERF_RECORD_MISC_KERNEL (1 << 0)
#define PERF_RECORD_MISC_USER (2 << 0)
#define PERF_RECORD_MISC_HYPERVISOR (3 << 0)
We need to compare against the complete value of cpumode,
otherwise hypervisor samples get incorrectly attributed as
userspace.
