Debian ISO: advertise wrolpi.local with Avahi (#839)

Browse source 
INSTALL.md and the onboarding wizard send people to wrolpi.local, but the
Debian image had no mDNS responder, so the name never resolved on a Debian
install or Live USB.  Raspberry Pi OS ships Avahi; the ISO now does too.

libnss-mdns lets the WROLPi's own desktop resolve .local names (apt
recommends are off in the build, so it is listed explicitly).  check-iso.sh
fails the build if either package is missing.
