B #112: Move script location outside of /tmp

Introduce new OpenNebula directory /var/lib/one-context where a new tmp
directory is located. This new one will not be mounted with noexec
option on any system by default.

Add cleanup handler on the script exit and ensure the correct return
code for the init scripts (if one or more fail then return non-zero).

Update onesysprep and set its version by generate.sh script.
