Function read_tmpfiles

crates/tmpfiles/src/lib.rs:500–512

Read all tmpfiles.d entries in the target directory, and return a mapping from (file path) => (single tmpfiles.d entry line) This function reads from both `/usr/lib/tmpfiles.d` and `/etc/tmpfiles.d`, with `/etc` entries taking precedence (matching systemd's behavior).
