[meta-virtualization][PATCH] k3s: fix systemd service install

[Adrian Freihofer <adrian.freihofer@gmail.com>]

- sed was complicated and fragile
- sed runs on k3s-agent.service before it was installed
- not all paths were replaced
- "if systemd in DISTRO_FEATURES" is already handled in systemd.bbclass
