promql: copy data when short-circuiting (cherry pick)

Bryan Boreham c2efd5bf96 promql: copy data when short-circuiting (#9552)
* promql: copy data when short-circuiting

Because the range query loop re-uses the output buffer each time round,
we must copy results into the buffer rather than using input as output.

Merge pull request #21 from grafana/reuse-expand-postings-method-in-new-postings-cloner

Use ExpandPostings() in NewPostingsCloner()
We should reuse that method, not only because it saves code, but also
because that method is a good candidate to use a pool of slices some
day.

Test that approxBytesPerEntry const is correct
The comment on the constant mentions where it comes from, so we can
actually check its value in that test.
