reftable/merged: simplify indices for subiterators

When seeking on a merged table, we perform the seek for each of the
subiterators. If the subiterator has the desired record we add it to the
priority queue, otherwise we skip it and don't add it to the stack of
subiterators hosted by the merged table.

The consequence of this is that the index of the subiterator in the
merged table does not necessarily correspond to the index of it in the
merged iterator. Next to being potentially confusing, it also means that
we won't easily be able to re-seek the merged iterator because we have
no clear connection between both of the data structures.

Refactor the code so that the index stays the same in both structures.
