font-patcher: Correct python module missing message

Browse source 
[why]
When the fontforge python bindings are not installed we fail while
importing psMat. The message suggests that fontforge itself is not
installed - which is not the real reason. One can use the libfontforfge
with the python-fontforge without having the GUI program fontforge.

Furthermore we link to outdated installation instructions.

[how]
We already check and report correctly what needs to be done with the
fontforge module import. As both modules are often in the same package
we should probably report the same message. That message holds correct
hints for Debian/Ubuntu. It does not have a link to fontforge, though.

[note]
Also update Debian package name.

Fixes: #725
