Subject: [PATCH] sg_inq: udev-conformant character encoding for --export

The '--export' switch prints out values suitable for direct
udev import. As such we should be using an udev-conformant
character encoding to avoid clashes with the original scsi_id
and also to ensure the string can be used to generate a
symlink.
