tests/docker: Install Sphinx in the Ubuntu images

Since commit 5f71eac06e the Sphinx tool is required
to build the rST documentation.

This fixes:

 $ ./configure --enable-docs

 ERROR: User requested feature docs
        configure was not able to find it.
        Install texinfo, Perl/perl-podlators and python-sphinx
