ktest.pl: Check kernelrelease return in get_version
commit a4e17a8f239a545c463f8ec27db4ed6e74b31841 upstream.
In the case of a test that uses the special option ${KERNEL_VERSION} in one
of its settings but has no configuration available in ${OUTPUT_DIR}, for
example if it's a new empty directory, then the `make kernelrelease` call
will fail and the subroutine will chomp an empty string, silently. Fix that
by adding an empty configuration and retrying.
