Rename camera struct typedef from cam to cam_t

Depending on the gcc options, that causes a fatal warning:

v4l.c:36:37: error: declaration of ‘cam’ shadows a global declaration [-Werror=shadow]
 static void insert_resolution(cam * cam, int x, int y)
                               ~~~~~~^~~
In file included from v4l.c:6:
v4l.h:99:3: note: shadowed declaration is here
 } cam;
   ^~~
