spec: drop/update dependencies on systemd-{units,sysv}
spec: drop/update dependencies on systemd-{units,sysv}

-sysv was probably a left-over, and the -units deps was outdated and not
necessary, see
https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_dependencies_on_the_systemd_package.

Only for 'systemctl mask' which is executed in %post, we want to make
sure that /usr/bin/systemctl is installed, so keep that dependency.
(A file dep is used to avoid issues if the systemd package is further
split later on.)

Ferried over from https://src.fedoraproject.org/rpms/libvirt/pull-request/7.
