fixed: commit f86225e and package blacklisting:

Don't remove /tmp/pkg/list_deps_busy until the loop in list_deps() has finished,
or get_deps() will carry on too early, and miss downloading all the deps needed.

Fixed pattern for matching blacklisted packages - this means some packages that
were being wrongfully hidden are now OK. Specifically, this fixes installing
Krita on Fossapup64, which now finds and pulls in all deps.
