Update nslcd conf to avoid ldap lookups for local groups

Currently when there is no ldap configuration,
nslcd daemon starts with default config which has
URI ldap://127.0.0.1, then we notice unnecessary nslcd
LDAP lookups for all local groups.

this commit updates config with "nss_initgroups_ignoreusers ALLLOCAL"
this option filters out all LDAP lookups for all local groups.

Tested by:
1.reboot system and check traces
2.restarting nslcd service and check traces
