HP-UX: Drop support for building CMake on HP-UX

Browse Source 
CMake will soon require both C++11 and libuv to build.  Neither of
these works on HP-UX, so unfortunately we need to drop support for
the platform until someone can get them working.

drop-HP-UX
----------
* Support for building CMake on HP-UX has been dropped pending better
support for C++11 and a port of libuv. See `CMake Issue 17137`_.
Use CMake 3.9 or lower instead for HP-UX support.
