quirks: lower AttrTrackpointMultiplier for ThinkPad X200/201 to 0.25

Browse source 
Upstream commit 43cd2cbf83 ("data: add the dell trackpoint multipliers")
broke the default acceleration profile on Lenovo ThinkPad X200/201, where
the cursor speeds became so quick that it was practically impossible to
control. Merely dragging on the TrackPoint lightly would result in the
cursor flying from corner-to-corner.

I have tested on a Lenovo ThinkPad X201 to find
`AttrTrackpointMultiplier=0.25' the most reasonable and closest to the
default behaviour on Windows 7 with Lenovo's driver.

Not sure about ThinkPad X200s/201s, but I suspect that they would have
similar issues (with the multiplier set to 1.25). I have just ordered both
models to experiment with and will report back with another patch if I
find similar issue.
