shill: Clear PMKSA cached credentials on unload
When an 802.1x WiFi service Unload()s, ask wpa_supplicant to clear
all cached credentials. This is a workaround for dropping PMKSA
cache entries in wpa_supplicant when the user logs ouut. Newer
versions of wpa_supplicant will support dropping cache entries
automatically when netblocks are changed. This will allow more
granular key clearing.
