[LTP] [PATCH] adding s390x tests to ltp

The reason, why I suggested to move these tests to upstream [1]
is that testing "vmcp --version" or "vmcp --help" does not really depend on
anyhow on SUT. Adding it to upstream into make check (there are none check yet)
would bring 1) earlier catch of potencial bugs as upstream developers can run it
for each commit (CI) and distros during package build.

We had some discussion before about removing some user space packages [2].
Cyril suggested to to keep tests that are working with files (cp/df/ln)
and remove at least unzip and wc.
Doing some real testing (really using vmcp.ko) would make this tests useful to
run on LTP, but current code IMHO does nothing with kernel. Or do I miss
something?

Anyway, it looks like you have no objection about adding it to LTP, so I changed
state of this test New. In that case, I suggest to

remove debugging:
> +#set -x
> +#

use tst_res TINFO instead of echo
+	echo "verifyBasicVMCPCommands"
+	echo "verifyErrorCondition"

Kind regards,
Petr
