Make LINUX_VERSION_PROBED compatible with loglinear

If we use loglinear, we need to stop it from redirecting stdout if we
want to capture stdout via the "shell" command. We do so by setting the
environment variable LOGLINEAR_LEAVE_STDOUT. Previously,
LINUX_VERSION_PROBED was always empty because of this bug.
