lib: add tst_kvercmp2 to compare specific vendor extra kernel versions
We can now test specific verdor kernel versions in
test cases like:
static struct tst_kern_exv exv[] = {
{"RHEL6", "234"},
{"SLES10", "0.91"},
{NULL, NULL}
};
...
if (tst_kvercmp2(2, 6, 25, exv) < 0)
...
...
Thank you for Cyril's suggestion.
