switch bugzilla names over to misc-web

for T1237 to let phabricator handle old
bugzilla URLs and redirect them via mukunda's script

can't just be I092e89ee21441 because iridium doesn't
have a public IP

so it should need this instead and another change in
the varnish config to send it over to iridium as a backend

also: does the script handle all 3 names we are switching here?

bugs. and bugzilla should be switched, bug-attachments
is supposed to stay per comments here and on Ib4dc0e16572da7ec6
