[GENERAL] Fix setting of HELM_VER variable

It turns out that helm v2 and helm v3 uses different format for the
helm version command. If we use v3 version HELM_VER variable is empty
when run on a system with helm v2.

To fix this let's add a fallback and if we failed to obtain correct
version information using v3 format then fallback to v2 one.
