gnu: Use #:prefix when importing (guix licenses).

This works around a problem with #:hide, whereby Guile would report
'zlib', 'openssl', and/or 'expat as colliding bindings at run time
despite the #:hide.

* gnu/packages/linux.scm: Use #:prefix license for (guix licenses).
* gnu/packages/haskell.scm: Likewise.
