pax: exit 0 if stdin filelist is used and empty 

If copying a list of files from stdin, exit zero instead of non-zero
if there are no files supplied.

AFAICT, POSIX doesn't require a non-zero an error in this situation,
since there are no files to not match.

Fix from PR bin/41736 by Lloyd Parkes.
