CLOUDSTACK-7143: use shar to inject cloud-scripts from working copy

The current build downloads its script from master by fetching a cloudstack
tarball. Besides being an unneeded load on the apache git server, this is a
problem when working on a branch and wanting to inject a different set of
scripts. It also makes it pretty likely that the injected copy of the script
will not match what a production release wants, so there is very little
chance of not needing to overwrite the scripts.

Ideally we would just rsync over some files. However, veewee does not provide
an option to do that. In order to keep a 'cleanly veewee-only' build possible,
and work with any recent veewee version, in this change we restor to using
shar (http://en.wikipedia.org/wiki/Shar) to produce an archive which can
execute as a script, which we feed to veewee to execute.
