kernel-devsrc.bb: Replace extra System.map file with symlink

Browse Source 
Currently there are two .map files being copied to $kerneldir/build.
One of the files is System.map and the other is
System.map-<kernel version>. Each .map file takes up about 5MB and
have identical sha256sum hashes. This change will make it so only
System.map-<kernel version> is copied in order to save disk space.
It also recreates System.map as a symlink to that .map file.
