Revert 187554 "Implement IPC::ChannelFactory, a class that accep..."

Reverting because it seems to cause failures on ipc_tests
(UnixDomainSocketUtil.Connect, UnixDomainSocketUtil.SendReceive) on Android.

> Implement IPC::ChannelFactory, a class that accept()s on a UNIX socket.
> 
> IPC::ChannelFactory listens on a UNIX domain socket and notifies its delegate
> when a client connects. The delegate is expected to craft an IPC::Channel from
> the handle it is given.
