Update get version script for snapshots

The current script assumes that snapshot versions are always available.
However the Linux Foundation has now implemented a policy of deleting
snapshots on no-master branches that are older than a certain age. THis
breaks our CSITs.

THis updated script copes with this by checking if a snapshot is
avaialable and, if the snapshot is not available, the script falls back
to the released version.

This script will be needed on other branches besides master as well.
