localmodconfig: Add debug prints for dependencies of module configs

When a config for a module is added to the list to save in the final config file, add a print to show what dependencies are used. This is useful to debug when a config is disabled by the make oldconfig after localmodconfig is finished. This print only appears if the environment variable LOCALMODCONFIG_DEBUG is defined.
