Integrate libjpeg-turbo at Ubuntu LEB

Registered by Ricardo Salveti

Integrate libjpeg-turbo library by default at the Ubuntu LEB, replacing the old libjpeg library (as it's ABI compatible).

This will increase the jpeg encode/decode performance at the whole image, by numbers described at https://wiki.linaro.org/TomGall/LibJpegTurbo

Whiteboard

Headline: libjpeg-turbo is now available at the Ubuntu LEB, replacing the old libjpeg62 and delivering a wide range of optimizations (as described at https://wiki.linaro.org/TomGall/LibJpegTurbo) for every application using the system jpeg library.
Acceptance: Ubuntu LEB image delivers libjpeg-turbo integrated by default, working same way as the old libjpeg62 library (100% compatibility is expected). Package integrated and available at Ubuntu LEB at least 2 test iteration before the 11.07 release, so it can be properly tested for regressions.
