Auxio would usually open links by trying to walk through the app
chooser/default app situation themselves, mostly for compat purposes.
This method was not only broken in Android 11 with the addition of
the QUERY_ALL_PACKAGES permission, but it also seems to be made
obsolete since the android system seems to handle the app choser
pretty well in 11+. As a result, we replace the link opening code on
that version with a plain startActivity call and keep the old compat
code for older versions.
Resolves#47.
