daemon: Remove OpenSSL hash compatibility wrappers.

* nix/libutil/hash.cc (struct Ctx): Copy from gcrypt-hash.hh.
(start, update, finish): Use gcrypt functions directly instead of
OpenSSL-like wrappers.
* nix/libutil/gcrypt-hash.cc, nix/libutil/gcrypt-hash.hh,
nix/libutil/md5.h, nix/libutil/sha1.h, nix/libutil/sha256.h,
nix/libutil/sha512.h: Remove.
* nix/local.mk (libutil_a_SOURCES, libutil_headers): Adjust
accordingly.
