spatial svc: remove vpx_svc_get_message

Print error messages as they are encountered. This was the default
behavior.

Removes a static analysis warning regarding the use of strncat:
Null pointer argument in call to string length function

As this is the only use of strncat in the library, remove it and the
associated public function.
