Previously, in a networking-less environment such as 'guix shell -C -D guix', 'guix refresh --list-updaters' would crash due to a 'gettaddrinfo-error' exception in these predicates. * guix/gnu-maintenance.scm (%gnu-updater)[pred]: Wrap in 'false-if-networking-error'. (%gnu-ftp-updater)[pred]: Likewise.
