Bug 1405087: Also nix -moz-user-input: enabled. r=bz

It only has one use, has the same effect that "auto", and should have no effect
in <a> elements anyway (plus it's not overridden or used in that file at all
anyway), so we can remove its only use instead.

I can also change that use to "auto" if you want, but bug 760876 doesn't mention
-moz-user-input at all, so I think this is quite useless...

See the intent to unship for research on out of the tree usage:
