Subject: Use _NSGetEnviron on Mac OS X to gain access to environ.

When building nvim as a shared library for testing, environ is not
exposed.  In order to gain access to the environment variables, you must
get a pointer to them from _NSGetEnviron().

It appears that this may affect the FreeBSD platform too.
