Fix aa_log_end_msg() in rc.apparmor.suse

"rcapparmor kill" results in a funny error message:
    /lib/apparmor/rc.apparmor.functions: line 441: return: -v: invalid option
    return: usage: return [n]

SLE12 includes a patch that prevents this error message, but also
prevents that $? is handed over correctly to rc_status. This means that
"rcapparmor kill" will happily display "done" even with a compiled-in
apparmor module that can't be unloaded.

This patch is the improved version - it adds a small helper function to
set $? (as handed over to aa_log_end_msg()) and then calls rc_status -v.
This means that "rcapparmor kill" now shows "failed" because it's
impossible to unload something that is compiled directly into the
kernel.
