Rename the Python 2 package to python-speechd
    
    This makes the Python module naming consistent with other distros;
    I've checked Debian, openSUSE, and Mageia and they all use
    python-speechd for the Python subpackage name.
    
    Having less differences between distros makes it easier for upstream
    projects that use this (Orca) specify the deps in their documentation.
    
    The new naming is also blessed by the Fedora Packaging Naming Guidelines
    (http://fedoraproject.org/wiki/Packaging:NamingGuidelines).
