In commit https://github.com/linux-can/can-utils/commit/b153fe3f3591
("clang-tidy: sort includes alphabetically") the position of the "lib.h"
include has been moved in a way that struct canfd_frame has not been
defined anymore and lead to a warning when compiling cangen.c
This patch reverts that specific move and unifies the location of local
includes at the end of the include list.

Using j*smthng* for j1939-related tools is not very good for 2 reasons:
1. j prefix is not very informative;
2. jcat name is used by journal cat tool from popular sleuthkit toolkit;
2`. jacd sounds very similar to jackd.
2``. Possible future name conflicts for new tools.
Thus I renamed j* to j1939\1 to deal with this issue.
