Fix issues of dependencies and QA of ALS/CES2016 demo

Fix issues of dependencies and QA of ALS/CES2016 demo

This patch fixes these issues:
 - The packages qtmultimedia-qmlplugins,
   qtquickcontrols-qmlplugins and qtsvg-plugins are missing

   For RDEPENDS_${PN},
     PN="ALS2016-demo" and PN="CES2016-demo" not work
     PN="als2016-demo" and PN="als2016-demo" work

   Probably root cause would be in elsewhere...

 - Many QA warning while copying ALS/CES2016 demo files
