unix: always use fstatat(AT_SYMLINK_NOFOLLOW) over lstat on AMD64

Browse Source 
ARM64 does this exact same thing, and in fact this is required on
Android 9, where Bionic now only allows lstat on 32-bit platforms
Folks are running into this when using Android on Chromebooks,
which are keeping AMD64 Android alive. So, we change the AMD64
behavior to model that of ARM64.
