* vfs/extfs/iso9660.in (test_iso): Use `locale charmap' to retrieve

the current character set. If that fails fallback to using
the LC_CTYPE field of `locale' output.
When invoking `isoinfo' to test whether it supports a given character
set tell it to use /dev/null as the cdrom device so that it will bail
out immediatly instead of accessing a real drive.
