Include Solaris kernel headers

Add the Solaris kernel headers used be the userspace tools to the
distribution. The same setup as used by Linux is taken. We modify the
Linux kernel headers to also install in /usr/include/xen/sys/ -
without a kernel-neutral path, it can make using the headers very
difficult, and encourages errors.
