sysstat: Correct our systemd unit file
In commit
8862f21e (sysstat: 12.1.3 -> 12.1.6), sa_lib_dir was changed
from "${libdir}/sa" to "${libexecdir}/sa" to avoid problems with
multilib. However, the systemd unit file was not changed accordingly,
which lead to the following error when trying to start the service:
systemd[4698]: sysstat.service: Failed at step EXEC spawning
/usr/lib/sa/sa1: No such file or directory
