perf env: Move arch errno function to only use in env

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".
