includes: install them

This commit installs the required include files needed for CDE
development.  In pre-autotools CDE, these were installed in
/usr/dt/share/include/ and a symlink was created in /usr/dt/include to
point toward them.

This is no longer done, and all include files are just installed in
${prefix}/include/ like the rest of the planet.
