At least on RedHat the run-parts command is very precarious and doesn't
even check for the return code of the scripts it runs causing the
dib-first-boot to delete itself even when something went wrong with the
configuration of the first boot of the image. Using the dib-run-parts
instead will make the whole first boot routine to be more robust and
less platform dependent.

Setting up a routine to run at first time the system boot may vary from
distribution to distribution. This patch will remove the logic from the
diskimage-builder code and put it into the elements.
The base element will now deploy a dib-first-boot script and each OS
element will ensure that this script runs at rc.local time. By doing
that we will put the OS specific stuff in the OS elements and remove
the embedded code out of the img-function file.
