    Do not fail in absence of versioninfo

    The tar command used do get the versioninfo content does not just
    return empty when versioninfo is absent: it fails, triggering
    set -e protection and resulting in the whole script failing. Fix
    makes sure the command is successful (by || true) even when it
    returns nothing.

    Fixes bug 1018820
