Firejail rejects empty arguments

[reinerh]

A Ubuntu user reported that firejail rejects arguments to the application if they are empty.
But for some applications empty arguments are actually valid use cases.
Even with the argument separator (--) firejail still rejects it.

Example:

$ echo ''

$ firejail -- echo ''
Error: too short arguments
$

This is the location of the check:

firejail/src/firejail/main.c

Lines 1027 to 1030 in e66ba7c

	if (*argv[i] == 0) {
	fprintf(stderr, "Error: too short arguments\n");
	exit(1);
	}
