Move arch_syscalls__strerrno_function out of builtin-trace.c to env.c so that there isn't a util to builtin function call. This allows the python.c stub to be removed. Also, remove declaration/prototype from env.h and make static to reduce scope. The include is moved inside ifdefs to avoid, "defined but unused warnings".
