cansniffer: fix gap calculation output

Browse Source 
The gap between two consecutive frames of a specific has been calculated in
handle_timeo() instead of handle_bcm() which lead to values that where
at minimum the loop time of the display refresh.

The effect can be seen when displaying a 10ms gap CAN frame with a 200ms
display refresh (option -l 20 => default) in opposite to a 10ms display
refresh (option -l 1).
