bozohttpd minor fixes to man page

[Swift Griggs <swiftgriggs%gmail.com@localhost>]

I like NetBSD's httpd. I noticed a couple of minor inconsistencies in the 
bozohttpd(8) manual page. Where should I report these?

* The -v option appears twice in the options summary. It's shown as both a 
  flag and a switch that takes options. They can't be both right. 

* The -V option is documented in the manual page, but does not appear in 
  the options summary block at the top of the manual page. It's also 
  unclear if "slashdir" is an option for -V or if the text refers to the 
  "slashdir" given as the document root.

* -V is also not documented in the usage when you get help directly from 
  the binary (ie.. just run /usr/libexec/httpd to see what I mean).
