Update prep_tarball script to download pre-exported documentation.

I've updated the prep_tarball script to now download the pre-exported documentation
from the Asterisk wiki. This will give us more control over what is being included
in the tarball releases, and will make both the PDF and HTML exported documentation
look much better (especially when viewing from a console).

(Closes issue ASTERISK-18677)
