android: fix avatar padding (#559)

Update Avatar to take isFocusable as a parameter, allowing us to make the avatar focusable in the main view but not in the settings / user switcher view. This fixes the issue where the padding is too big in the settings / user switcher view.

Fixes tailscale/corp#24370
