unix: always use inotify_init1 over inotify_init on AMD64

Browse Source 
ARM64 does this exact same thing, and in fact this is required on
Android 9, where Bionic now only allows inotify_init 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. However, since Go must run on
kernels between 2.6.27 and 2.6.23, we must still fall back to the
original call.
