Drop separation between BA and Go module sdk

Since BA and Go module sdk contain the same Apis, we no longer need to
maintain two separate SDKs.

Summary:
- rm -rf go/current
- remove blueprint_package_include from current/Android.bp. This ensures
  the soong modules in this Android.bp are not ignored when building go
devices.
