cam: Add optional argument to --capture to specify how many frames to capture
Extend the '--capture' option with and optional numerical argument to be
able to specify how many frames to capture before exiting. If the
optional argument is not provided the old behavior of running until the
user interrupts with a SIGINT is retained.
