CVE-2022-32746 ldb: Make use of functions for appending to an ldb_message

Browse Source 
This aims to minimise usage of the error-prone pattern of searching for
a just-added message element in order to make modifications to it (and
potentially finding the wrong element).

BUG: https://bugzilla.samba.org/show_bug.cgi?id=15009
