Scripts/check_leftovers.sh: Remove exceptions for GHC

These exceptions come from the era when we were packaging Haskell libraries.
Registering a Haskell library in the global store results in changes in
package.conf.d and doc directories.

We don't install Haskell libs anymore, so there is no need in these exceptions.
Moreover, both paths are now wrong, because:

- share/doc/ghc-%%GHC_VERSION%% was changed to share/doc/ghc
- lib/ghc-%%GHC_VERSION%%/package.conf.d was changed to lib/ghc-%%GHC_VERSION%%/lib/package.conf.d
