Fix behaviour of -Wunused-packages in ghciwip/unused-package
Ticket #21110 points out that -Wunused-packages behaves a bit unusually
in GHCi. Now we define the semantics for -Wunused-packages in
interactive mode as follows:
* If you use -Wunused-packages on an initial load then the warning is reported.
* If you explicitly set -Wunused-packages on the command line then the
warning is displayed (until it is disabled)
* If you then subsequently modify the set of available targets by using
:load or :cd (:cd unloads everything) then the warning is (silently)
turned off.
This means that every :r the warning is printed if it's turned on (but you did ask for it).
Fixes #21110
