eap: look for the realm of anonymous identity as wellandroid13-dev
Some carriers won't ask for real identity at the beginning,
they will use anonymous identity instead,
ex. anonymous@wlan.mncXXX.mccYYY.3gppnetwork.org.
In this case, wpa_supplicant should look for the realm of
anonymous identity to decorate new pseudonym.
Bug: 233283842
Test: verify roaming flow: AP1 -> AP2 -> AP1 -> AP2
