There does not seem to be an easy way to achieve this.

For archives (the /nar/foo URLs), there is currently no ‘Content-Length’
header at all (this is because Hydra, the software, generates those
files on the fly; we should tweak nginx to add a ‘Content-Length’
header, but this seems to require an external nginx plugin.)
However, the {mirror.,}hydra.gnu.org use chunked encoding, indeed, which
allows the HTTP client to detect truncated transfers.
