[PATCH SYSTEMD 2/7] selinux: improve debug log format

["Christian Göttsche" <cgzones@googlemail.com>]

path might be NULL when checking against the system permissions, so wrap
with strna().

The command line might not be available over D-Bus and thus cl might be
empty.  To improve readability quote the corresponding value.
