imlib2: imlib2-config: delete old reference to @my_libs@

The script "imlib2-config" returns "@my_libs@" that causes build failures
on the programs that use it.
This is a regression of version v1.4.6.

Add a upstream patch to fix it and reorder the patches to follow
upstream branch order.

 This is set up in config.h by configure, so avoid defining it again.
