wg-quick: darwin: prefer system paths for tools 

The only things wg-quick(8) needs from Homebrew are bash(1) and wg(8).
Other than that, it's explicitly coded against the native system
utilities. Since wg-quick(8) and bash(1) are invoked in auto_su by their
full absolute path (via $SELF and $BASH, respectively), we can simply
set the $PATH to be prefixed by the default system binary paths. This
way, if users install tools that conflict with system tools -- such as
GNU coreutils -- we won't accidently call those.
