odb: drop `loaded_alternates` field

The `struct object_database::loaded_alternates` field tells us whether
or not alternates have been loaded already. This field was useful before
the preceding commit as we were indeed lazy-loading alternates. But now
that we started to eagerly load them we can assume them to be loaded
after `odb_new()`, and hence the field does not serve any purpose
anymore.

Remove it.
