patch: --enable-tests and --only-dependencies

Hi there.

Same as "cabal install foo", but additionally add a constraint that
the testsuite stanzas for "foo" should be installed.

Will generate an install plan for package in the current directory,
enabling testuite stanzas for that package. Will subsequently try to
delete the package that is defined in the current directory from the
resulting install plan.

That should (still) work. If you have any evidence that it doesn't,
please let me know.

Cheers,
  Andres
