Include NAR size in fingerprint computation
This is not strictly needed for integrity (since we already include the NAR hash in the fingerprint) but it helps against endless data attacks [1]. (However, this will also require download-from-binary-cache.pl to bail out if it receives more than the specified number of bytes.) [1] https://isis.poly.edu/~jcappos/papers/cappos_mirror_ccs_08.pdf
