lib-storage: Use getuid() instead of geteuid() for checking if we're running as root.

This fixes running multiple doveadm commands for different users. Running
mail_storage_service_init() + _deinit() multiple times left euid non-root,
which dropped the MAIL_STORAGE_SERVICE_FLAG_TEMP_PRIV_DROP flag.
