daemon: Use 'int' instead of the internal 'gcry_md_algo_t' type.

Fixes compilation with the forthcoming libgcrypt 1.6.x.
Reported by Matthias Wachs <wachs@net.in.tum.de>
and NIIBE Yutaka <gniibe@fsij.org>.

* nix/libutil/gcrypt-hash.cc (guix_hash_init, guix_hash_final): Use
  'int' as the type of the 'algo' parameter.
* nix/libutil/gcrypt-hash.hh: Update declarations accordingly.
