r25218: After discussion with Simo, remove the subclass support from LDB.

Subclass support was designed to avoid needing to spell out the full
list of objectClasses that an entry was in.  However, Samba4 now
enforces this restriction in the objectClass module, and the way
subclass matching was handled was complex and counter-intuitive in my
opinion (and did not match LDAP).
