Return a cell name from afsconf_LookupServer

Previously, afsconf_LookupServer could not meaningfully return a cell
name, since a char* was passed in for realCellName, and
afsconf_GetAfsdbInfo was expecting the value of the pointer to change.
Change afsconf_LookupServer to take a char**, and pass realCellName by
reference, so we can get a cell name back.
