install-qa-check.d/60pngfix: parallel support (bug 630292)
If xargs supports the --max-procs option then use the makeopts_jobs function from helper-functions.sh to generate a --max-procs argument. Use xargs -L 1 to limit the number of png files per pngfix process, in order to ensure that enough processes are spawned, since otherwise xargs minimizes the number of processes spawned. A benchmark with flightgear-data-2018.2.1 shows that larger values of -L only decrease performance.
