Rework the J1939 and ISO TP feature enabling logic in config.cmake to: - define WITH_FEATURE_J1939 and WITH_FEATURE_ISOTP to default to off, thus requiring explicit enabling. This is safer than making assumptions based solely on the presence of the headers at build time. - honor WITH_FEATURE_* definitions given on the cmake command-line; the checks for header presence only over-ride an "ON" value if the required header is not present. Bug-AGL: SPEC-3538 Signed-off-by: Scott Murray <scott.murray@konsulko.com> Change-Id: Ie2b84ac50bbed0bbb775cae49f7f4fbe14f2f8ae
