Subject: Fix mDNS, hostname, and build safety

- Add safe_cleanup_work_dir() to prevent /dev corruption on interrupted builds
- Fix shadow file: use sed to modify root entry instead of replacing file
- Add /etc/hosts and /etc/nsswitch.conf for proper hostname/mDNS resolution
- Add inetutils package for hostname command
- Add sanity tests for password, avahi, mdns, and hostname
