tools: kwboot: Allow to use -b without image path as the last getopt() option
Currently it is possible to call "kwboot -b -t /dev/ttyUSB0" but not to
call "kwboot -b /dev/ttyUSB0".
Fix it by not trying to process the last argv[], which is non-getopt()
option (tty path) as the image path for -b.
Fixes: c513fe47dca2 ("tools: kwboot: Allow to use option -b without image path")
