push-notification-lua: Use the new accessor functions instead of variables directly

This fixes plugin dependency checking. Instead of:

Fatal: Couldn't load required plugin .../lib22_push_notification_lua_plugin.so: dlopen() failed: /usr/local/lib/dovecot/lib22_push_notification_lua_plugin.so: undefined symbol: event_category_push_notification

The error is now clearer:

Fatal: Couldn't load required plugin .../lib22_push_notification_lua_plugin.so: Plugin push_notification must be loaded also
