[PATCH] testsuite/xeno-test: Stop systemd-timesyncd across smokey runs

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

With dovetail, clock_settime affects the Linux wall clock as well. When
systemd-timesyncd is running, the posix-clock test will fail because its
check of clock settings will immediately be overwritten by timesyncd
again. So stop that service if present and running and restart it after
the test.
