Input: do not use property bits when generating module alias

The commit 8724ecb0

 ("Input: allow matching device IDs on property
bits") started using property bits when generating module aliases for input
handlers, but did not adjust the generation of MODALIAS attribute on input
device uevents, breaking automatic module loading. Given that no handler
currently uses property bits in their module tables, let's revert this part
of the commit for now.
