lib/oe/patch.py: Dont import patches but symlink them instead
* This patch removes the usage of quilt import <patch>
instead it creasted a symlink to the patch in the patches
directory and synthesizes the series file which otherwise
would be done automatically by quilt import.
* This should help a bit in reducing build time as it avoids
copying of the patch and also other things that quilt import
would otherwise do.
* Tested by doing minimal-image on qemuarm.
