This patch adds support for installing the latest Security World client
software. The installation media format for that version is a zipped
file containing an ISO.
The mechanism for installing the source media was changed to expect this
new format. The file is still downloaded to the target host and now
unzip is used instead of tar to unarchive the ISO.
The client software is now installed on the target host using the RPM files
found in the ISO image.
