David James 359d3e119d Simplify boilerplate common.sh code in src/scripts.
Currently, the scripts in src/scripts have multiple implementations
for handling when common.sh fails to load, some of which are buggy.
To simplify the boilerplate, these scripts now just exit if common.sh
fails to load. The shell itself will print the following message if
common.sh is not found:
  /usr/lib/crosutils/common.sh: No such file or directory

BUG=chromium-os:32442
TEST=Run these scripts with and without common.sh installed.
