Fix android bluetooth permission request above api version 30

The BLUETOOTH permission was removed in api version 30 in favor of
BLUETOOTH_SCAN, BLUETOOTH_ADVERTISE and BLUETOOTH_CONNECT.

This means that manifests targetting api version above 30 will not have
this permission set. For these versions the manifest should be checked
for the new permissions.

This change ensures that the documented behavior of the bluetooth
permission always returning `true` is true.

Fixes issues Baseflow#884
