Remove HP-UX port.

Browse Source 
HP-UX hardware is no longer produced, build farm coverage recently
ended, and there are no known active maintainers targeting this OS.
Since there is a major rewrite of the build system in the pipeline for
PostgreSQL 16, and that requires development, testing and maintainance
for each OS and tool chain, it seems like a good time to drop support
for:

 * HP-UX, the operating system.
 * HP aCC, the HP-UX native compiler.
