add python-vte to sysdeps

[sascha_silbe]

Pippy doesn't start because the Python module vte is missing:

Traceback (most recent call last):

File "/home/sugar/sugar-jhbuild/install/bin/sugar-activity", line 21, in <module>

main.main()

File "/home/sugar/sugar-jhbuild/install/lib/python2.5/site-packages/sugar/activity/main.py", line 105, in main

module = import(module_name)

File "/home/sugar/sugar-jhbuild/install/share/sugar/activities/Pippy.activity/pippy_app.py", line 26, in <module>

import vte

ImportError: No module named vte

Please add it to the sysdeps files. For Debian+Ubuntu, it's probably in python-vte (package exists, but haven't tested yet).

OK, python-vte is the right one for Ubuntu (and thus Debian). But two others are missing as well:
- pygame (python-pygame on Debian/Ubuntu)
- gst (python-gst0.10 on Debian/Ubuntu)
