tinycap, tinyplay: Check *argv before dereferencing.

In several places, argv is incremented and *argv is dereferenced
without checking to see if it is valid to do so.  This could lead to a
buffer overrun if the user provides invalid parameters.

This patch generally changes this:

    if (strcmp(*argv, "-r") == 0) {
        argv++;
        rate = atoi(*argv);
    }
    argv++;

To this:

    if (strcmp(*argv, "-r") == 0) {
        argv++;
        if (*argv)
            rate = atoi(*argv);
    }
    if (*argv)
        argv++;
