docs: properly geneate man page

* Makefile.am (INSTALL_SCRIPT): Re-define to our wrapper.
* auxdir/our-install-sh: New wrapper around 'install -c'.
* doc/Makefile.inc: Ensure manpage source is referenced with
leading $(builddir) variable.
* postgresql-setup.in: Add build-time only function which
translates install-time dirs into source dirs.
