unix: add AT_EACCESS on Darwin

MKuranowski · MKuranowski · commit 28082ec1509c · 2023-03-29T12:42:28.000+09:00
The AT_EACCESS constant, used by faccessat syscall is present on Linux, Solaris and other BSD platforms. This commit also adds this constant on Darwin. The constant (and the associated faccessat syscall) is part of POSIX.1-2008. Fixes golang/go#59265.
