Fixed error in cpac_install.sh script (contained in cpac_install_ubuntu.tar.gz)

Previously, script was attempting to download file named "cpac_image_resources.zip", which no longer exists.

Instead, similar file named cpac_resources.tgz now exists.

Because the .tgz file is binary, I'm pasting the diff of the affected file below
