feat: use pure-Rust libsystemd crate (#11163)

This drops the `systemd-rs` family of crates in favor of `libsystemd`, a
pure-Rust alternative: https://github.com/lucab/libsystemd-rs

This crate has more recent activity (2 months ago vs 11 months ago for
systemd-rs) and does not require C bindings.

The `libsystemd` BUILD files are still required for `infogetty`.
