falco: tune out calibre sudoers-sed and lsyncd log-truncation false positives

Investigated recent Telegram alerts - no intrusion, both new hits trace to
benign one-offs: calibre's linuxserver.io s6-init NOPASSWD setup (same
pattern already whitelisted for obsidian) and lsyncd truncating its own
status log (not evidence-clearing).
