scripts: sphinx-pre-install: fix PDF build issues on Ubuntu

PDF output with current Debian-based distros require other
packages for it to work. The main one is pzdr.tfm. Without
that, \sphinxhyphen{} won't work, affecting multiple docs.

For CJK, tex-gyre is required.

Add the missing packages to the list.

After the change, all PDF files build on latest Ubuntu:
