packaging: Remove symbolic link in a devel package

packaging: Remove symbolic link in a devel package

The symbolic link to kernel-devel-tizen-dev doesn't need anymore because
those who want to build SWAP-DA will use the absolute package name for
building respectively on the several kernels.

The out-of-tree kernel module build uses absolute devel package name to
bulid SWAP-DA. It should be left out to prevent a conflict between
each kernel devel packages.
