services.flix: don't fail flix-index when a file vanishes mid-scan
/var/download churns constantly (download temp files appearing and
vanishing), so `find` exits non-zero when an entry disappears between
readdir and stat. Under `set -efu` that aborted the oneshot, which during
a nixos switch counted as a failed unit and flipped the whole switch to a
non-zero exit. Tolerate find's exit code and only replace the live index
if a non-empty listing was produced.
