fix(etc-drift): tolerate no-match grep and whitespace-separated MODIFIED

- grep exits 1 when pattern has no matches; under pipefail that killed
  the recipe. Wrap both pipelines in `{ ...; } || true`.
- pacman -Qii can separate MODIFIED from the path with spaces or a tab
  depending on formatting; use \s+ instead of \t.
