Q matrix: use radio.config@1.2::IRadioConfig

1.1 IRadioConfig does not exist. radio.config@1.2 is a
minor version uprev that only updates the sub interfaces,
not the top level interface.

Test: builds
Test: on device with target-level 4, w/o this change,
      with radio config 1.1, see test failure on deprecated
      radio config HAL
Test: on this device, with this change, with radio config 1.1,
      deprecated radio config HAL failure goes away.
