Update sockopt-timestamp test Pick up the upstream commit v5.13-10-g0211fdc "tests: change sockopt-timestamp test to use syscall(__NR_recvmsg)" and augment it with an additional fix to actually tests SO_TIMESTAMP* socket options. * 0141-tests-change-sockopt-timestamp-test-to-use-syscall-_.patch: New file. * 0154-tests-call-setsockopt-directly-in-sockopt-timestamp.patch: Likewise. * strace.spec (Patch141, Patch154): New patches. (%prep): Apply them (%changelog): Mention the change. Resolves: #1996676 Signed-off-by: Eugene Syromiatnikov <esyr@redhat.com>

From 9aada05f4c7f95220a5b16416f530419db6b4dff Mon Sep 17 00:00:00 2001
From: "Dmitry V. Levin" <ldv@strace.io>
Date: Fri, 23 Jul 2021 08:00:00 +0000
Subject: [PATCH] tests: change sockopt-timestamp test to use
syscall(__NR_recvmsg)
Since the glibc recvmsg wrapper became unsuitable for our needs,
invoke __NR_recvmsg syscall directly.
* tests/sockopt-timestamp.c: Include "scno.h" and <errno.h>,
conditionalize on __NR_recvmsg.
(TEST_OLD_SCM_TIMESTAMPS): Remove.
(k_recvmsg): New function.
(test_sockopt): Use it instead of recvmsg.
