setterm: segfault with long dump file name

The patch will make too long path to be truncated to MAX_PATH
lenght. If user supplies too long file name that is caught at
fopen. Some users might find this unintuitive, so the altered
behavior will be mantioned in manual page.

Bug in earlier version was visible with a command bellow.

setterm -dump -file $(for i in $(seq 254); do printf x ; done)
