shinano-common: Import and bind mount loader config for media swcodec

 * This config needs to be modified for legacy devices. As
   there is no easy way to split it, import it into device
   tree and bind mount it instead.

 * Head at android-10.0.0_r2
   (3ac371484399da6efbd0c835aa461d3326263ab1).
