libs: encoder: jpeg: set component id and Tqi

Browse source 
This change is due a problem encoding JPEGs with Intel's
media-driver: green/black image when playback jpeg

This patch sets component identifier and quantization table
destination selector in frame header to support packing headers
by Intel's media-driver that does not accept packed header
in AP level.
