nss: Turn __nss_database_lookup into a compatibility symbol
The function uses the internal service_user type, so it is not really usable from the outside of glibc. Rename the function to __nss_database_lookup2 for internal use, and change __nss_database_lookup to always indicate failure to the caller. __nss_next already was a compatibility symbol. The new implementation always fails and no longer calls __nss_next2. unscd, the alternative nscd implementation, does not use __nss_database_lookup, so it is not affected by this change.
