[nrf fromlist] Bluetooth: Tester: Increase config values to make tests pass

Without this PTS tests do not pass. These values are copied from a
commit aimed at unifying the prj.conf files in this directory. I do not
know which of these are strictly necessary to make the tests pass.
Copying them all poses no harm since the unification will be done later
anyway.
