[PATCH olang v1 3/3] docs: remove pandoc dependency for man docs

[Johnny Richard <johnny@johnnyrichard.com>]

Pandoc is an excelente tool and works pretty well, but I think it's
overkill to keep it just for create a manpage.  The man pages should be
pretty simple to create using the roff syntax so lets keep things
simpler with less dependency.
