Properly partition the build system and install some missing stuff:

* Introduce targets base-build and db-build.
* Introduce targets base-install and db-install.
* Introduce a BUILD_TARGETS variable to contain db-build.
* Introduce an INSTALL_TARGETS variable and fill it using BUILD_TARGETS.
* Install the apropos(1) and mandocdb(8) binaries.
* Install whatis(1) as a hard link to apropos(1).
* Install the apropos(1), whatis(1), and mandocdb(8) manuals.
* Install mandoc_aux.h.
