For an unknown reason, "cabal sdist" does not include the file
hashed-storage/Bundled/sha2.h in its output tarball, while
it seems to know how to handle other header files in darcs' code.
I realised that hashed-storage did not switch to cryptohash
as did darcs with the patch "replace C SHA256 bindings with
external libraries" in 2012.
So this patch does the same for hashed-storage. Along with
solving (avoiding) the "cabal sdist" bug, it saves us one
module.
