Add CAN_J1939 as module to default build configs (#4346)

There is a CAN protocol named J1939 which is supported by Linux Kernel
since v5.4. Recently J1939 header file turned up in
raspberrypi-kernel-headers but the module is not built for kernel
v5.10.y due to the missing flag. Therefore set it to build as module:

CONFIG_CAN_J1939=m
