Calle Wilund aaa25e1a78 Commitlog replayer: Range-check skip call ...

Fixes #15269

If segment being replayed is corrupted/truncated we can attempt skipping
completely bogues byte amounts, which can cause assert (i.e. crash) in
file_data_source_impl. This is not a crash-level error, so ensure we
range check the distance in the reader.

v2: Add to corrupt_size if trying to skip more than available. The amount added is "wrong", but at least will
    ensure we log the fact that things are broken

Closes scylladb/scylladb#15270
