avformat/mpegtsenc: do not include adaptation field in teletext TS packets
From ETSI EN 300 472 V1.3.1 (2003-05) Specification for conveying ITU-R System
B Teletext in DVB bitstreams:
4.1 Transport Stream (TS) packet format
The standard TS packet syntax and semantics are followed, noting the following
constraint:
- adaptation_field_control only the values "01" and "10" are permitted.
Some set top boxes (Motorola, Arris, Zyxel) refuse non-conforming packets.
