[VirtioWifi] Add p2p-wlan\d-.* Pattern in Tethering Config

Emulator Wi-Fi driver only supports wlan0 interface which operates in
both sta and p2p mode. Becausse default config_tether_wifi_p2p_regexs
doesn't include the p2p-wlan\d-.* pattern, tethering would not work on
Emulator under this rule.

Also, Tethering package is APEX and we need to create a RRO to overwrite
the values for config_tether_wifi_regexs and config_tether_wifi_p2p_regexs.
