Make LocalBinaryCacheStore::narFromPath() run in constant memory
This reduces memory consumption of
nix copy --from file://... --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79
from 514 MiB to 18 MiB for an uncompressed binary cache, and from 192
MiB to 53 MiB for a bzipped binary cache. It may also be faster
because fetching can happen concurrently with decompression/writing.
Continuation of 48662d151bdf4a38670897beacea9d1bd750376a.
