wifi-scripts: fix failing mesh setup with missing wpa_supplicant

The initialization of mesh interfaces currently fail when wpa_supplicant
is not installed. This is due to the script calling the wpa_supplicant
feature indicator without verifying wpa_supplicant is installed at all.

To avoid failing, first check if wpa_supplicant is installed before
determining the available featureset.
