[PATCH] dpkg: Fix internal deb import for sbuild

[Uladzimir Bely <ubely@ilbers.de>]

Directory "/var/cache/apt/archives" may not exist under sbuild env
(for example, when sbuild chroot was taken from sstate-cache), so
deb import doesn't properly work in this case. This makes apt
download packages from external mirror instead of using cached
files.

Also, stop masking (with "|| :" any possible errors while importing
and exporting *.deb files to/from sbuild environment.
