bug#29219: CUPS filter still can't access Ghostscript (gs)

Just make sure to reconfigure from a recent-enough commit (run ‘guix
--version’ as root to see which commit you’re using.)

If it turns out you’re already using CUPS with commit
1728c411718e3b358c06561d6e80b47d7b331617, could you reproduce the issue
while running “strace -p PID -f -s 345 -o log”, where PID is the PID of
cupsd as shown by ‘herd status cups’?

TIA!

Ludo’.
