build: prevent unused-parameter warning

the connectivity bt_le_adapter has auto generates files
  - bluez-glue.c
  - object_manager-glue.c

The files are included when building the connectivity_abstraction
library. This error is only disabled when bt_le_adapter is being
built. We don't want to hide the unused-parameter warning. This
is the simplest way to hide the warning without large changes
in the build.
