Subject: Process token IDs from id.def without id.h

Fixes id.h error during updating ripper.c by `make after-update`.

While it used to update id.h in the build directory, but was trying to
update ripper.c in the source directory.  In principle, files in the
source directory can or should not depend on files in the build
directory.
