fix(android): disable Impeller on Sony audio players and Vivante GPUs

The GL renderer string is empty when Flutter shell args are built (no GL context yet), so the GPU-pattern check never matched Sony Walkman devices and Impeller crashed in the Vivante driver's glLinkProgram. Match MANUFACTURER 'SonyAudio' (distinct from Xperia 'Sony') and add Vivante GC GPU patterns.
