perf/core: Wire up compat PERF_EVENT_IOC_QUERY_BPF, PERF_EVENT_IOC_MODIFY_ATTRIBUTES

Since pointer size is different in compat, and switching in _perf_ioctl
is done using exact ioctl numbers, all new ioctl numbers that use pointer
should be added to perf_compat_ioctl for _IOC_SIZE fixup before passing
to perf_ioctl routine (this shouldn't be needed if semantics of the size
argument of _IO* macros was honored).
