Subject: [PATCH] scripts/checksyscalls.sh: only whine perf_counter_open when supported

If the port does not support HAVE_PERF_COUNTERS, then they can't support
the perf_counter_open syscall either.  Rather than forcing everyone to add
an ignore (or suffer the warning until they get around to implementing
support), only whine about the syscall when applicable.
