s3-passdb: Respect LOOKUP_NAME_GROUP flag in sid lookup.

Somewhere along the line, a config line like "valid users = @foo"
broke when "foo" also exists as a user.

user_ok_token() already does the right thing by adding the LOOKUP_NAME_GROUP
flag; but lookup_name() was not respecting that flag, and went ahead and looked
for users anyway.
