systemd: Order wpa_supplicant before network.target

Ordering the units before network.target causes them to be stopped
after network.target on shutdown. This ensures that any network
filesystems will be unmounted before wpa_supplicant is killed.

Adding Wants=network.target ensures that network.target will be included
in the active dependency graph. This is typical of units which are
involved in networking setup functions.
