fpsensor: export matched finger index
Update the fingerprint match event to include the index of the template
which matched.
Signed-off-by: Vincent Palatin <vpalatin@chromium.org>
BRANCH=poppy
BUG=b:77516790
TEST=on ZerbleBarn, enroll 5 fingers and do matching from the console,
see the proper finger index in the trace.
TEST=on Meowth, check unmodified biod still works for match with the
updated MCU firmware.
