sdap: properly handle binary objectGuid attribute
Although in the initial processing SSSD treats the binary value right at some point it mainly assumes that it is a string. Depending on the value this might end up with the correct binary value stored in the cache but in most cases there will be only a broken entry in the cache. This patch converts the binary value into a string representation which is described in [MS-DTYP] and stores the result in the cache.
