Fix build failure due to Debian 11.3. The failure is caused
by us building 247.3-6, while the the package builder was
trying to install systemd 247.3-7 which caused the packages
to fail.
One of the benefits of this is that the systemd-timesync patch
we carry was able to be dropped because it was included
in the latest update.
Test Plan
PASS Build and Install systemd package
PASS Run build-pkgs -a
