Input: i8042 - make Lenovo 3000 N100 blacklist entry more specific

Apparently, there are more different versions of Lenovo 3000 N100, some
of them working properly with active mux, and some of them requiring it
being switched off.

This patch applies 'nomux' only to the specific product name that is
reported to behave badly unless 'nomux' is specified.
