check_whence: error if symlinks are in-tree 

Currently we have no symlinks in-tree. Add a simple check, ensuring they
don't get added in the future.

This allows us to remove the clunky symlink checking code in
copy-firmware.sh

v2:
 - tweak helper to produce link and target (based off Adam's patch)

v3:
 - honour quoted target/linkname
