navidrome: repair root-owned data folders left by 0.61.x

Navidrome 0.61.x created cache, artwork and plugins under the data
folder whenever any navidrome command ran, including the ones the deb
postinstall runs as root. 0.62 stopped creating them that way but never
corrected the owner, so a container that passed through 0.61.x carries a
root-owned artwork directory. 0.64.0 is the first release to write into
it and fails with

  writing image store: mkdir /var/lib/navidrome/artwork/hashed:
  permission denied

which breaks newly resolved album covers and every playlist cover, since
those are composites.

Repair the three directories the same way navidrome/navidrome#6143 does:
the entries themselves only, since they were created empty, real
directories owned by root only, and chown -h, because the navidrome user
owns the data folder and could otherwise plant a symlink.

The trailing || true is not in the upstream copy and is needed here.
Their postinstall runs without set -e, while update_script runs under
catch_errors, which sets -Ee with an ERR trap. find exits 1 as soon as
one starting point is missing, so on a container without a plugins
directory the update would abort.

Fixes the report in #17247, confirmed there by the reporter's stat and
dpkg log: artwork is root-owned and dated to their 0.60.3 -> 0.61.1
upgrade.
