[Cin] blds/bld_prepare.sh update

Hi, attached is an update blds/bld_prepare.sh script. It has two changes: - Extra entries to install the patchelf, boost_regex and boost_filesystem packages. - A fix for Suse, the test for the link was failing. @Andrea, did not have time to add an Arch/Manjaro section. Suse installs all packages, but it fails on the linking stage of the new makeappimage tool. Have to look at it. MatN
