tests: relax test download remote layers api (#7604)

Browse Source 
## Problem
This test triggers layer download failures on demand. It is possible to
modify the failpoint
during a `Timeline::get_vectored` right between the vectored read and
it's validation read.
This means that one of the reads can fail while the other one succeeds
and vice versa.

## Summary of changes
These errors are expected, so allow them to happen.
