apcupsd: add powerfail logic at shutdown

This implements the behavior described in the upstream documentation:
https://web.archive.org/web/20230206010908/http://www.apcupsd.org/manual/manual.html#verifying-a-source-installation

Also patch the doc/Makefile to not generate *.man.txt files which are
only needed for the MinGW platform and depend on the deprecated `col`
command.
