mercurial.spec: rename docutils to python-docutils in BuildRequires

Even though the name of the project is Docutils, most packagers use
the package name python-docutils to fit into the naming scheme of
other packages written in Python.  The name is used by Fedora, EPEL,
DAG, Mandriva, and a few other distributions.

 # From the README:
 #
 #   Note: some distributions fails to include bits of distutils by
 #   default, you'll need python-dev to install. You'll also need a C
 #   compiler and a 3-way merge tool like merge, tkdiff, or kdiff3.
 #
 # python-devel provides an adequate python-dev.  The merge tool is a
 # run-time dependency.
