The `perf` util currently has a incomplete implementation for the
following event flags, that events with these flags will be dropped or
be identified as unknown types:
`PERF_CONTEXT_GUEST_KERNEL`
`PERF_CONTEXT_GUEST_USER`
This patch makes `perf script`, `perf timechart` and `perf data`
to correctly identify these flags.
