[PATCH] hwsim tests: use tshark -Y instead of tshark -R

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

Newer versions of tshark don't like the -R (read filter) argument
for filtering and just show a deprecation warning. Use -Y (display
filter) instead, which hopefully also works on older versions.
