apparmor_parser "hides" error message in help output

[Christian Boltz]

# /sbin/apparmor_parser -r /etc/apparmor.d/bin.ping # running as _user_
/sbin/apparmor_parser: Sorry. You need root privileges to run this program.

AppArmor parser version 2.9.1

Usage: /sbin/apparmor_parser [options] [profile]

Options:
--------
[...]

The parser errors out for obvious reasons, but why does it hide the
"You need root privileges" message behind the full --help details?

IMHO it should _only_ print the "You need root privileges" message.

BTW: The same happens for apparmor_parser --unknown-option.

BTW2: maybe you should also update the copyright year ;-)
