Tast: add pirika and pirette to skip in Wifi80211ax hwdep

The dedede models pirika and pirette use WiFi chipsets which do not
support 802.11ax, and thus should be skipped in the Wifi80211ax hwdep.

Tested on pirika and pirette DUTs.

BUG=b:196835822
TEST=tast run $DUT wifi.HeCaps
wifi.HeCaps  [ SKIP ] ModelId matched with skip-on list
