Temporarily make sure contact area is always defined

Some devices do not always send touch_minor after touch_major
has been set. According to the MT protocol, this case should
be treated as if minor is equal to major. This patch makes sure
touch_minor is never zero when touch_major is set.

When grail v1.0.13 is out, this patch will no longer have any effect.
