Mingli Yu 6f0b28f009 logrotate.py: restore /etc/logrotate.d/wtmp
During the test logrotate.LogrotateTest.test_1_logrotate_setup,
there is below logic:
 # mkdir $HOME/logrotate_dir
 # sed -i "s#wtmp {#wtmp {\n    olddir $HOME/logrotate_dir#" /etc/logrotate.d/wtmp

After all logrotate.LogrotateTest finished, only cleanup
$HOME/logrotate_dir as below, but don't restore
the config file /etc/logrotate.d/wtmp.
[snip]
def tearDownClass(cls):
    cls.tc.target.run('rm -rf $HOME/logrotate_dir')
[snip]

That's to say, there is one additional line added
to /etc/logrotate.d/wtmp and will make the logrotate
service start failed when run systemd.SystemdBasicTests.test_systemd_failed

Take an example as below when run test as root:
 # cat /etc/logrotate.d/wtmp
 # no packages own wtmp -- we'll rotate it here
 /var/log/wtmp {
    olddir /root/logrotate_dir
    missingok
    monthly
    create 0664 root utmp
    minsize 1M
    rotate 1
 }

 # ls /root/logrotate_dir
 ls: cannot access '/root/logrotate_dir': No such file or directory

 # systemctl start logrotate
 Job for logrotate.service failed because the control process exited with error code.
 See "systemctl status logrotate.service" and "journalctl -xe" for details.

Add the logic to restore /etc/logrotate.d/wtmp to
make the cleanup complete to fix the above issue.
