[Intel-gfx] [PATCH v3 18/19] test-dyndbg: tune sub-module behavior

lib/test_dynamic_debug.c is used to build 2 modules:
test_dynamic_debug.ko and test_dynamic_debug_submod.ko

Define DEBUG only in the main module, not in the submod. Its purpose
is to insure that prdbgs are enabled by default, so that a modprobe
without params actually logs something, showing that compile-time
enablement works. This doesn't need to be repeated in the submodule.

Rather, the submodule's purpose is to prove that classmaps defined and
exported from a parent module are propagated to submodules, setting
their class'd debugs accordingly.
