Will Woods 27dda6eae6 ppc.tmpl: work around yaboot's crippling fear of backslashes
If yaboot so much as catches a whiff of a backslash in yaboot.conf, it
will reject the entire file. No bootloader config means no booting.

So as long as we're still using yaboot on PPC, we need to use ISO volume
labels it can handle. So: filter the isolabel, replacing any non-ASCII
characters with underscores.

## ofboot.b picks one of /ppc/ppc{32,64}/yaboot.conf for yaboot,
