sys-kernel/coreos-kernel: copy vmlinux and vdso libs into /usr/lib/debug

Browse Source 
This shouldn't affect the SDK or the OS image, but ensures that debug
symbols are available from the binary package.

vmlinux is installed to:

    /usr/lib/debug/usr/boot/vmlinux-<version>

vdso binaries are installed to:

    /usr/lib/debug/usr/lib/modules/<version>/vdso/

A symlink is created:

    /usr/lib/debug/usr/lib/modules/<version>/vmlinux ->
    ../../../boot/vmlinux-<version>
