btrfs-progs: move the check_argc_* functions into utils.c

To let the independent tools(e.g. btrfs-image, btrfs-convert, etc.)
share the convenience of check_argc_* functions, just move it into
utils.c.
Also add a new function "set_argv0" to set the correct tool name:
	*btrfs-image*: too few arguments

The original btrfs* tools work as before.
