Uploads through RcatSize with a known size - used by rcat --size, the
rc operations/uploadfile and the serve backends, eg serve restic - did
not check the size of the uploaded object. If the source stream ended
before the declared size worth of data had been read, the truncated
object was reported as a successful upload. This could corrupt data
for callers which trust the result, eg a restic repository accessed
via serve restic (see #9722).
This adds the same size check operations.Copy performs after a copy,
respecting --ignore-size and backends which do not report sizes.
