rax-dns-backup: fix parsing

It looks like at some point the RAX bind output changed format
slightly, which messed up our backup script.  Rework it to parse the
current output.

This parsing is obviously a little fragile ... it is nice to have the
output sorted and lined up nicely (like our manually maintained
opendev.org bind files...).  If the format changes again and this
becomes a problem, maybe we switch to dumping the RAX output directly
and forget about formatting it nicely.
