systemd/postmarketos-base-systemd: depend on kbd (MR 6029)

These were dropped from the systemd package when they should have been
moved here to pmos-base-systemd. Without this, systemd-vconsole-setup
crashes because it cannot find the kbd utility, and kmod is needed for
proper auto-module loading.
