[bug#36246] [PATCH] guix import hackage: Add two expected failing test cases.

[Robert Vollmert <rob@vllmrt.net>]

This adds failing test cases for two hackage import bugs:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25138
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35743

* tests/hackage.scm: Make comment style consistent. Add two
cabal parsing tests, marked as expected failures.
