cmd/gomobile: use standalone NDK toolchains

Issue golang/go#24058 demonstrates a Go package that fails to build with
gomobile but builds successfully with a manually using the standalone NDK
toolchain. I haven't been able to figure out a set of CPPFLAGS/LDFLAGS
that fixes the build for 24058 so instead rework gomobile to use
standalone NDK toolchains.

Standalone toolchains fixes the 24058 build and is the official way
to build Android programs. So gomobile should be less affected by
future changes in the NDK toolchain internals.

Create the standalone toolchains with gomobile init.

With the new Go 1.10 build cache, the prebuild work by the gomobile
init command is useless. Use the opportunity to simplify init to
only creating NDK toolchains and, optionally, building OpenAL for
Android. With that, it is no longer necessary to use gomobile init
to build iOS apps and frameworks.

Fixes golang/go#24058
