Cocoa: Remove tablet event warnings.

Browse Source 
Qt warns on all touchpad evens when running in a VM.
This appears to be harmless. Remove the warning.

Also, qWarnings are ideally messages to the application
developer about incorrect use of Qt API. In this case
there is nothing the application developer can do
and a qWarning is not really appropriate.

Task-number: QTBUG-36484
