Add TW_IGNORE_ABS_MT_TRACKING_ID 

Fixes touch on Oppo R7 Plus

Oppo R7 Plus, when recovery is flashed and booted from the actual
recovery partition, the digitizer sends some extra touch data for
up to 10 different touch slots even if no actual touch is present
for those slots (ABS_MT_SLOT). This patch allows TWRP to handle
touch data properly for this device and maybe others.
