Remove RECORD_AUDIO requirement for ST listModules

No reason to require RECORD pre-flight permissions to query dsp module
properties. CAPTURE_AUDIO_HOTWORD, which is a non-runtime permission,
should suffice to ensure only valid ST clients can call this method.

We will still require RECORD for the rest of the methods, which actually
begin to interact with the hardware.
