wpa_cli: Support action scripts with global ctrl_iface

Browse Source 
This extends "wpa_cli -a<action script>" functionality to work with the
global wpa_supplicant control interface. The IFNAME=<ifname> prefix is
removed from the event messages and converted to the control interface
name when present. Previously, action scripts could only be used with
the per-interface control interfaces.
