mpegtsparse: fix handling of TOT and TDT sections. Fixes #635281.

TDT and TOT sections, with PID=0x14, doesn't extend to several packets
and the section filter is not needed here and shouldn't be used at all
for these tables because the have a different structure.
For example, TDT tables were not parsed for odd hours because this bit
is the 'current_next_indicator' bit for the other sections, and the table
was discarded.
