Fix environ enumeration on Apple platforms

Summary:
environ is documented to not work very well from .dylib-s (dynamic libraries) on macOS. Use the _NSGetEnviron function instead to get a pointer to environ.

<crt_externs.h> is missing from some iOS SDKs, so forward-declare _NSGetEnviron in such cases.
