wifi-scripts: add sae_track_password option

This is useful if multiple passwords were specified without
the use of a SAE password identifier. This is the only
way to get multiple passwords for a single peer to work
without resorting to password identifiers.

Unfortunately, support for password identifiers is non-existent
on Android and macOS; and possibly others. So this is the only
option in that case.

As an alternative, one could also continue to use WPA2-PSK instead
as that could easily resort to a bruteforce approach without any
complications.
