Brian Harring d5d5dbffa1 Fix/standardize exiting if common.sh can't be found
The problem here is that most were doing their exiting w/in a subshell;
exit within a subshell kills the subshell, not the parent.  Not all scripts
were using set -e (which would pick up the failing subshell); as such
just rewriting them to remove the potential via eliminateing the subshelling.

Beyond that, removed a couple of custom (working, although non-standard)
approaches, and removed a duplicate common.sh sourc'ing w/in mk_memento_images.sh

TEST=force 'find_common_sh' to fail, note the scripts fails to exit
BUG=none
