wpa_supplicant: Changed systemd template units

I goofed up the scissor line on the last attempt. Not sure how much it matters,
but here it is correct this time.

Here it is, updated to work with wpa-supplicant_2.6.bb.

When building root filesystems with any of the wpa_supplicant systemd
template service files enabled (current default is to have them disabled) the
systemd-native-fake script would not process the line:

Alias=multi-user.target.wants/wpa_supplicant@%i.service

appropriately due the the use of "%i."

According to the systemd documentation "WantedBy=foo.service in a service
bar.service is mostly equivalent to Alias=foo.service.wants/bar.service in
the same file." However, this is not really the intended purpose of install
Aliases.

All lines of the form:

Alias=multi-user.target.wants/*%i.service

Were replaced with the following lines:

WantedBy=multi-user.target
