test-runner: Only create/remove interfaces for hostapd

Browse Source 
Move the interface creation code from configure_hw_radios to
configure_hostapd_instaces so as not to create unneeded interfaces on
the wiphys that IWD is going to manage.  We pass a wiphy whitelist to
IWD later and IWD now creates the interfaces it needs on those managed
wiphys.  Change TEST_WIPHY_LIST format to only include the interface
name for the wiphys used by hostapd.

Note that we still remove interfaces just before removing the hwsim
radios on exit, it seems like there's no point removing the interfaces
in that case.
