[PATCH v4 2/2] Ensure generation of /etc/os-release is idempotent

[Felix Moessbauer <felix.moessbauer@siemens.com>]

Prior to this patch, the generation of the os-release file
was not idempotent as there was a name-glitch in VARIAN_VERSION.
By that, the script did not detect an existing VARIANT_VERSION
and add one additional one per invocation.
