cmd/dist: restore GOARM=7 default for android/arm

Browse source 
Fixes the android/arm builder. Without it, the builder reported
unexpected stale targets during bootstrap:

https://build.golang.org/log/b951f1171be54cf4a12c2a0720ffaf07f8a11377

Tighten the GOARM=7 default in cmd/internal/objabi while here.
