[PATCH] tests: fix mbo_assoc_disallow on old tshark

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

Older tshark seems to be a bit inconsistent. It returns the timestamp
with a timezone qualifier, but then doesn't accept it when passed in the
same format. Use the frame number instead of the timestamp to work
around that.
