Add init fragment for hostapd on Android

This fragment defines how the Android init system should start hostapd
as a standalone service.  Previously, hostapd was fork/exec'd from
Android's netd.  This left hostapd with some dangling file descriptors
and a process parent minimally interested in acting as init for child
processes.
