wpa_supplicant: Try all drivers by default

Browse source 
Some distros carry patches to specify driver fallback, but only in
specific conditions (e.g. the systemd service definition[1]). This leaves
other wpa_supplicant instances needing to define fallback themselves,
which leads to places where wpa_supplicant thinks it can't find a
driver[2]. Instead, when -D is not specified, have wpa_supplicant try
all the drivers it was built with in an attempt to find a working one
instead of just giving up if the first doesn't work.
