perf script: Allow showing the --switch-on event
One may want to see the --switch-on event as well, allow for that, using
the previous cset example:
# perf script --switch-on syscalls:sys_enter_nanosleep --show-on-off
sleep 13638 [001] 108237.582286: syscalls:sys_enter_nanosleep: rqtp: 0x7fff1948ac40, rmtp: 0x00000000
