[PATCH nft 04/11] tests/shell: fix handling failures with VALGRIND=y

[Thomas Haller <thaller@redhat.com>]

With VALGRIND=y, on memleaks the tests did not fail. Fix that by passing
"--error-exitcode=122" to valgrind.

But just returning 122 from $NFT command may not correctly fail the test.
Instead, ensure to write a "rc-failed-valrind" file, which is picked up
by "test-wrapper.sh" to properly handle the valgrind failure (and fail
with error code 122 itself).

Also, accept NFT_TEST_VALGRIND_OPTS variable to a pass additional
arguments to valgrind. For example a "--suppressions" file.

Also show the special error code [VALGRIND] in "run-test.sh".
