preload: generate manpage when not cross
https://github.com/void-linux/void-packages/pull/44038

Description:
If `help2man` isn't available at build time then the contents of man8/preload.8 are:

> help2man is required to generate this file.

 Apparently `makewhatis` has to run after the new file is installed so `man` knows to run the file through the formatter but I'd rather not add a post-install script.

This also adds psmisc to checkdepends because the test script uses `( sleep 1; killall ./preload 2>/dev/null ) &` to ensure the test ends.
