avformat/jacosubenc: Fix writing extradata

Browse Source 
The terminating '\0' is no longer included in the size of
the extradata output by the demuxer since commit
36e61e24e7ac737b38c4382d439329352d9e0c29.
E.g. if one remuxes the JACOsub sample JACOsub_capability_tester.jss
from the FATE suite, one receives a file not recognized as JACOsub
before this patch.
