[PATCH] daemons/getty: display /etc/issue if available

Previously, a banner was hardcoded in Hurds getty. Load /etc/issue instead. Fall back to a hardcoded version if that fails. Expand common \char sequences. If no /etc/issue is provided, the old behavior is retained. * daemons/getty.c (load_banner): New function. (print_banner): Expand \char seq
