nss: Directly load nss_dns, without going through dlsym/dlopen
This partially fixes static-only NSS support (bug 27959): The dns module no longer needs dlopen. Support for disabling dlopen altogher remains to be added. This commit introduces module_load_builtin into nss/nss_module.c, which handles the common parts of loading the built-in nss_files and nss_dns modules.
