Fix branding in the update prompt on Android

Currently, the update prompt only refers to password manager as "Smart Lock" if
the PasswordBranding experiment group is SmartLockBranding. The save prompt and
both prompts on all other platforms (desktop + iOS) also accept the group
SmartLockBrandingSavePromptOnly.

This CL fixes the Android update prompt to follow the rest.
