Debian/Ubuntu: Install Droid fonts instead of symlinking.

The packaging/deb scripts create symlinks to Droid fonts that are no
longer available on Debian or Ubuntu. However, mythtv already has the
Droid fonts and installs them when mythtv is built from source.
This commit changes the debian/ubuntu packaging to install mythtv's
droid fonts instead of relying on fonts that were deprecated two years
ago and replaced by dejavu fonts that don't look right.
