Elias Naur e3d99a3f86 misc/android,cmd/dist: move $GOROOT copying to the exec wrapper 
To run the standard library tests on Android, the androidtest.bash
script copies GOROOT to the device. Move that logic to the android
exec wrapper, thereby making androidtest.bash obsolete.

Apart from making Android less special, the sharded builder
infrastructure should now be able to run (emulated) Android builders
and trybots without special treatment.

Updates #23824

README 

Android
=======

For details on developing Go for Android, see the documentation in the
mobile subrepository:

	https://github.com/golang/mobile

To run the standard library tests, enable Cgo and use an appropriate
C compiler from the Android NDK. For example,

	CGO_ENABLED=1 \
	GOOS=android \
	GOARCH=arm64 \
	CC=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
	./all.bash

To run tests on the Android device, add the bin directory to PATH so the
go tool can find the go_android_$GOARCH_exec wrapper generated by
make.bash. For example, to run the go1 benchmarks

	export PATH=$GOROOT/bin:$PATH
	cd $GOROOT/test/bench/go1/
	GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
