Subject: [PATCH] FST: detect detectors with no raw data also on macOS

The check for detectors that produced only empty raw files compared the
output of wc -l with "0". BSD wc, as on macOS, pads its count with
spaces, so the comparison never matched and an empty raw output went
unnoticed: the TRD raw files of a run were all empty, and the test only
failed later, when no CTF had been written. grep -c prints the bare count
on every platform.
