libwbclient needs to connect to the winbind socket. To find the winbind socket 
inside of selftest it uses:

if (nss_wrapper_enabled()) {
	env_dir = getenv("SELFTEST_WINBINDD_SOCKET_DIR");
}

So we need the NSS_WRAPPER variables to "enable" nss_wrapper. This way wbinfo 
connects to the right winbindd ...
