We're about to run self-hosted Android and iOS builders (#31722). It would be nice if Go could produce internally linked binaries for those platforms, for a less hacky bootstrapping and for being able to build x/build/cmd/buildlet and stage0 everywhere. Depends on #31343 Android.

cmd/link: default to internal linking for android/arm64
e6d7326 
The bootstrapping process (make.bash) on all other platforms use
internal linking. This change brings android/arm64 in line, fixing the
scary warning on our self-hosted Corellium builders:

warning: unable to find runtime/cgo.a

The linkmode default is changed to internal for all Android programs,
but in practice that won't matter outside our builders: using Go with
Android apps requires buildmode=c-shared which uses linkmode external.

Fixes #31343
Updates #31819
