refactor: Use NetworkErrorString for macOS code in netif.cpp

Browse Source 
Although these `sysctl` calls report generic system errors rather
than network errors, `NetworkErrorString()` is identical to
`SysErrorString()` on POSIX systems, so this does not change behavior.
It allows removing `#include <util/syserror.h>`, which was only needed
by `__APPLE__` code and would otherwise require an `#ifdef` guard to
silence an IWYU unused-include warning on other platforms.
