Sean Channel c65ffe9f7f admin/build-doc: Use installed Sphinx and its dependencies, when possible.
This avoids the delay of installing Sphinx inside the virtualenv;
especially, compiling lxml is slow.

If Sphinx is not installed system-wide (or it's too old), this will
still install a copy inside the virtualenv, to keep working.

Thanks to Sean for the push to make this happen, and testing the
various scenarios; I (Tv) took the liberty of changing the commit to
use venv-python for the manpage build too, avoid the nonstandard
"which" command, be more careful about quoting, and explain more fully
what's going on in the comment.
