samba: Switch back to builtin Heimdal Kerberos

When not building with the experimental (!!) system MIT Kerberos, Samba
will use the builtin Heimdal Kerberos. For this reason, enableKerberos =
true will still include a krb5 implementation, built right into Samba.

There is no benefit in using MIT krb5, however it has some downsides
like not being able to assign computer GPOs [1].

The ArchWiki [2] also mentions this in their installation section.
