[mediaplayer] Workaround for too sensitive touch move

When tapping youtube video play button we need
MotionEvent.ACTION_DOWN and MotionEvent.ACTION_UP sequence.
But we get MotionEvent.ACTION_DOWN, MotionEvent.ACTION_MOVE...,
MotionEvent.ACTION_UP and that doesn't work with play button.

This patch adds some treshold to motion event detection.

This is a temporary fix on application level. Issue should
be fixed properly in WPEView or in WebKit.
