input-capture: Fix off-by-one for barrier validation

Browse Source 
Assuming two 1920x1080 screens next to each other: a horizontal barrier
starting at 1920 going east is always outside the left screen.

Assuming two 1920x1080 screens on top of each other: a vertical barrier
starting at 1080 going south is always outside the top screen.
