Use a different LibreOffice ppa to install doxygen

Up to now we were using the LibreOffice 4.3 ppa (ppa:libreoffice/libreoffice-4-4) to install doxygen. The LibreOffice Packaging team appear to have removed this ppa, resulting in our doxygen build failing.

This changes the ppa we use to LibreOffice 4.4.x.
