doc: more minor updates

Remove all pandoc references.  We shouldn't need to clutter our
documentation with out-of-date references to pandoc, and pod2man is
probably widely-available enough that nobody should need to install
it.

Reduce HTTP redirects when linking to external sites.

It's also excessive to mention libkqueue as using the native
implementation (whether it be kqueue or epoll) is preferred
and easier.
