start-stop-daemon: Only create a link in ${base_sbindir} if necessary

If usrmerge is enabled in DISTRO_FEATURES, then ${base_sbindir} and
${sbindir} are set to the same path and the symbolic link from
${base_sbindir}/start-stop-daemon to ${sbindir}/start-stop-daemon can
(and should) not be created.
