Reland "Fix problem with ipv4 over ipv6 on Android"

This reverts commit 1e60490ddb11afecc796058802fbc80867d851d8.

Reason for revert: Downstream project has been fixed (127.0.0.1 is not PII)

Original change's description:
> Revert "Fix problem with ipv4 over ipv6 on Android"

> This reverts commit da2fd2a2b25ee4bd7b383424cb26d51fb6cc7716,
> as well as follow-up b7227a5a10f233cec04642f15a0233e7355bd340,

> Reason for revert: Breaks downstream test.

> First change's description:
> > Fix problem with ipv4 over ipv6 on Android
> >
> > This patch fixes a problem with using ipv4 over ipv6
> > addresses on Android. These addresses are discovered
> > using 'getifaddr' with interfaces called 'v4-wlan0' or
> > 'v4-rmnet' but the Android API does not report them.
> >
> > This leads to failure when BasicPortAllocator tries
> > to bind a socket to the ip-address, making the ipv4
> > address unusable.
> >
> > This solution does the following
> > 1) Insert BasicNetworkManager as NetworkBinderInterface
> > rather than AndroidNetworkManager.
> >
> > 2) When SocketServer calls BindSocketToNetwork,
> > BasicNetworkManager first lookup the interface name,
> > and then calls AndroidNetworkManager.
> >
> > 3) AndroidNetworkManager will then first try to bind
> > using the known ip-addresses, and if it can't find the network
> > it will instead match the interface names.
> >
> > The patch has been tested on real android devices, and works fine.
> > And everything is disabled by default, and is enabled by field trial.
> >
> > My plan is to rollout the feature, checking that it does not introduce
> > any problems, and if so, enabled for all.
