Subject: 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
