Subject: [PATCH] init-plex-chown/run: use TMPDIR instead of hardcoded
 /run/plex-temp

Changes init-plex-chown/run to use TMPDIR instead of hardcoded /run/plex-temp

Plex uses TMPDIR to store transcodes of music to WAV format for music
analysis (and maybe other things).

LS.io container sets TMPDIR=/run/plex-temp.  With read-only root this
means the /run tmpfs needs to have enough memory to store music analysis
transcodes.

LS.io container hardcoded /run/plex-temp in init so TMPDIR could not be
flexibly changed -- changed to use TMPDIR and clean on restart in case
of unclean shutdown.

Plex container is marked as supporting read-only root.
