c_client.py: Inject full_sequence into GE events

The generic event structure xcb_ge_event_t has the full_sequence field
at the 32byte boundary. That's why we've to inject this field into GE
events while generating the structure for them. Otherwise we would read
garbage (the internal full_sequence) when accessing normal event fields
there.
