Fix unbound variables in apt-{preferences,sources}

Browse Source 
Also make the apt-sources element exit with a non-error status code
when the DIB_APT_SOURCES is not set.

This allows including the apt-preferences and apt-sources elements
even if DIB_DPKG_MANIFEST and DIB_APT_SOURCES are not exported.
