Make apt::preferences_snippet place files in /etc/apt/preferences.d

Since Debian Squeeze, apt supports a .d directory for preferences
(pinning). Simplify management by just placing files inside this .d
directory.

This removes the need for concat and concat::fragment resources, so
removes the dependency on the concat module. It also removes the need
for a moduledir that was needed for the concat module magic, so we also
get rid of the dependency on the common module.
