s4:kdc: Have callers of samba_kdc_get_user_info_dc() themselves add an Asserted Identity SID

samba_kdc_get_user_info_dc() does too much. It should be responsible
only for getting account information, not for adding extra SIDs.

By extracting the call to samba_kdc_add_asserted_identity() into the
former function’s callers, we’ll be able to remove the
‘asserted_identity’ parameter in the next commit, reducing the
function’s complexity.
