Code review comment for lp:~ivaldi/midori/skip-plugin

This seems to break listing in about:version (we probably hardcode same string skip there. Would be nice to see how it behaves on the systems where 64 bit plugins dirs is just a symlink to 32 bit one (i think it was ubuntu). Otherwise it seems to work. Cannot get flash to work witn gtk3 but it is probably unrelated to this change.
