[OE-core] [RFC] rawcopy.py: Copy source file in image creation build folder

[Noor, Ahsan]

From: Noor <noor_ahsan at mentor.com>

* When a file is given using --sourceparams then wic directly use that file
  instead of copying them to build folder. At time of assmebling it os.rename
  is called which rename all the files to name. In that process the original
  file get renamed. When image recipe is rebuilt then wic complains about
  missing file which renamed in previous build.
