[PATCH 2/2] kernel-shark: Install public interface headers

[Yordan Karadzhov <ykaradzhov@xxxxxxxxxx>]

Installing the header files included in the public interfaces of
the KernelShark libraries will make possible the libraries to be used
for development.

A symbolic link that points to the latest versions of the libraries is
added to INSTALL_PREFIX/lib/kernelshark
