v4l2_stateful_decoder: fix short arguments a,c

-c and --capture_fmt should take an argument to specify the capture
queue's FOURCC. -a and --mmap should set the CAPTURE buffer type to
MMAP. However, the short arguments -c and -a weren't present.

Update the getopt string to match the case order and include the missing
options, c: and a.
