perf trace: Enclose all events argument lists with ()
So that they look a bit like normal strace-like syscall enter+exit
lines.
They will look even more when we switch from using libtraceevent's
tep_print_event() routine in favour of using all the perf beautifiers
used by the strace-like syscall enter+exit lines.
