 Testsuite: also normalise platform-dependent .stdout/stderr

 This effectively reverses commit
 429f0099ab9adfadc779ca76f3aae1c9c160fb8c (2006).

 I don't see why platform-dependent .stdout/stderr files should //not//
 get normalised.

 It fixes T11223_link_order_a_b_2_fail on Windows, by normalising
 `ghc-stage2.exe` to `ghc` when comparing stderr with .stderr-mingw32.
