[bug#39694] [SHEPHERD] [PATCH] build: Adjust clean targets.

[Efraim Flashner]

Makefile.am: Add man pages to the 'make clean' target.
---
Currently 'man shepherd' shows version 0.6.1, 'man herd' 0.6.0, 'man
halt' and 'man reboot' 0.3.2. With this patch these 4 manpages are added
to the 'make clean' list and are deleted. The manpage creation works as
expected.
