auto-t: add ability to reserve radios not for IWD/hostapd/etc

Commit Message

If the test needs to do something very specific it may be useful to
prevent IWD from managing all the radios. This can now be done
by setting a "reserve" option in the radio settings. The value of
this should be something other than iwd, hostapd, or wpa_supplicant.

For example:

[rad1]
reserve=false
