Unclobber dirs/Dirs in import XMonad

"dirs" is used several times in xmonad-contrib as a short for
"directions" and when I tried renaming those uses, I had a really hard
time coming up with something nice/meaningful. Therefore I think it's
best if we rename this instead, "dirs" is a valuable part of the
namespace. :-)

Fixes: 735fb58f6c ("Revise XDG handling")
