firmware-murata-infineon: generalize autocountry service

Make this service generic so it can be reused on every device containing
a Murata+Infineon chip.

In some platforms Worldwide pseudo-country could be 'XZ', in others it
could be 'WW'. Cover both of them.

In the meantime, improve the service to ensure the wifi device is
available by waiting for udev device discovery to settle, retrying
until the wireless interface responds to wl, and restarting the
oneshot unit on failure.
