Add CONFIG_MODULE_SIG_PROTECT to enable lookup for the unprotected
symbols from the build time generated list of symbols.
Module loading behavior will change as follows:
- Allows Android GKI Modules signed using MODULE_SIG_ALL during build.
- Allows other modules to load if they don't violate the access to
Android GKI protected symbols. Loading will fail and return
-EACCES (Permission denied) if these modules access the symbol which
is not allowlisted via symbol list or exported by a GKI module.

Script doesn't honor the Kernel's quiet command
mechanism with KBuild; so need to remove info
only echo. Added set -x in case make V=1 for keeping
debugging handy for script in the future.
