avfilter/avfilter: move enable_str expression parsing into avfilter_init_dict()

Browse Source 
This ensures that needed arrays are always allocated and properly initialized.

Previously if code would use only avfilter_init_dict() to set options for filters
it would not allocate arrays for timeline processing thus it would crash if
user supplied enable option for filter(s).
