Ensure that any APT's sources are deleted (a helper pkg for *-checkinstall pkgs).

This package is not intended for installation in normal systems.
Its sole purpose is to help the automatic testing of apt in hasher
with package repositiories where the default build env contains
uncommented external sources for APT (inaccessible in hasher).

For this package to have an effect at the moment when a *-checkinstall
package with tests for APT is installed, apt (and friends with sources.list)
must be installed in a separate previous transaction. (Otherwise
the effect would only happen at the end of the current transaction,
rather than before the testing scripts are run.)

A simple way to achieve this is to install this packages in a separate
transaction (and this package has a dep on apt).
