Show the "not actively monitored" banner on Android as well

[diox]

Fixes mozilla/addons#2207

The change should be straightforward enough to be verified by the unit test alone, and the issue explains the context a bit more, but if you want to check locally:

1. Visit /en-US/android/ with a Firefox for Android User Agent (on Desktop, Firefox responsive mode with some custom UA should do the trick)
2. Follow the link to a non-recommended add-on
3. Notice the "not actively monitored" grey banner is present
