unix: add perf event ioctl constants on Linux

Add the PERF_EVENT_IOC_* constants on Linux which are used to
enable/disable/configure perf events. Also add the PERF_IOC_FLAG_GROUP
constant which might be using as part of the ioct argument. See section
"perf_event ioctl calls" in
http://man7.org/linux/man-pages/man2/perf_event_open.2.html
