[klibc] dash: builtin: create builtins.c properly on old cpp

[ dash commit 35ff4d5b5a44aaf6fd98edef221dcc3ddcb8dda4 ]

Encontered this on ancient gcc-2.95.3 environment;
src/builtins.def.in -> src/builtins.def generation emitted
^ $
lines (likely by /* */), which where NOT ignored by
src/mkbuiltins and generating bogus builtins.c.
