Force "printing" if -T is specified, even if -w is also specified.

Just as "tshark ... -P -w xxx" writes raw packets to xxx *and* writes
text packet summaries to the standard output, and just as "tshark ...
-V -w xxx" writes raw packets to xxx *and* writes text packet details to
the standard output, so should "tshark ... -T fff -w xxx" write raw
packets to xxx *and* write whatever "-T fff" (and any "-e" options)
specifies to the standard output.
