    services: guix: Use the right locale package on GNU/Hurd.
    
    Fixes a bug introduced in 0dd293b4d9095137c9952e16ca951f887b7e7018
    whereby guix-daemon on GNU/Hurd would have ‘GUIX_LOCPATH’ set to the
    “wrong” locale data (2.35 instead of 2.37).
    
    Consequently, it would fail to setlocale(3) and calls to
    ‘std::stoi’ (when reading the output of ‘guix authenticate’) would
    throw, leading to this error message of guix-daemon:
    
      unexpected build daemon error: stoi
    
    This would manifest when sending store items to a childhurd:
    
      $ guix copy --to=localhost:10022 sed
      guix copy: sending 1 store item (1 MiB) to 'localhost'...
      guix copy: error: unknown error while sending files over SSH
    
    The “unknown error” is the ‘stoi’ exception.
    
    This commit fixes that, but for the ‘guix-daemon’ service only.
    
    * gnu/services/base.scm (guix-shepherd-service)[locales]: New variable.
    Use it instead of ‘glibc-utf8-locales’.
