Support multi-user scenario for local testing

**Is your feature request related to a problem? Please describe.**

Problem: Can't test non-primary user (=userId=0) case on Android

`install-apks` only pushes data to `/sdcard`, but `adb shell` only supports `/sdcard` for primary user.

**Describe the solution you'd like**

Take extra parameter `--user-id`, so data can be pushed to per-user storage (`/data/media/${user_id}/`)

**Additional context**

You can reproduce the issue by creating additional user, and try test app installation there.
