test-runner: Export final interface config to tests

Browse Source 
Communicate the final wiphy and interface configuration data after the
hostapd and iwd processes are started, to the test scripts as an
environment variable TEST_WIPHY_LIST.  This way the test scripts can
know which interfaces are used by hostapd instances, which hostapd
config they're using, and which are used by iwd.  The typical value will
be
rad0=wln0=hostapd,ctrl_interface=/var/run/hostapd,config=ssidOpen.conf
rad1=wln1=iwd
