Update manpages test for removal of config file check
Update manpages test for removal of config file check

This fixes the test suite for my previous commit, removing the
requirement for config files to have a manpage. One test was
specifically testing that check, so it is removed. Two other
tests relied on the behaviour, so I changed them to use an
executable under /bin instead of a config file.
