Disable alternative EAC3 fallback for EAC3-JOC streams on Pixel devices

Some Google Pixel devices integrate an EAC3 decoder that does not support
EAC3-JOC stream decoding. Playing EAC3-JOC streams on these devices fails
with a decoder error because ExoPlayer falls back to the alternative EAC3
MIME type.

This change disables the fallback to standard EAC3 for EAC3-JOC streams
on Google Pixel devices specifically, ensuring the player can select a
supported audio track (such as AAC) instead.
