[PATCH v2] meta/classes: Make sure the files exists before copying

[vijaikumar.kanagarajan@gmail.com]

From: Vijai Kumar K <Vijaikumar_Kanagarajan@mentor.com>

By default realpath doesnot check if the file exists and hence
might return an invalid path.

Check if file exists before copying.

Changes in v2:
  - Use -f in if condition instead of realpath -e to make code 
more readable.
