RPMs of the same name get installed only once. If something with the
same name ends up twice in the RPM database with different version
numbers, then this causes these kind of problems.

My suggestion is to run this:

rpm -e --justdb systemd-libs-219-42.el7_4.1.x86_64
yum update

This removes the *newer* RPM from the RPM database without actually
uninstalling any files and without performing any script actions that
usually might trigger during a real uninstall.

That leaves the older version of this RPM in the RPM database and during
the following YUM update newer version of this RPM will be installed again.

You could directly use "rpm -e --justdb ..." to remove the older RPM
from the database to resolve the conflict. However: Then you can't
really be sure if the newer RPM really got installed properly and that
all the things it was suppoded to do during RPM install were done.

For that reason I suggest the above way as it produces more reliable
results.
