HS 2.0: Add alternative OSU_SSID into providers info file

Browse Source 
This adds the second SSID (the one used by the shared BSS) for OSU
connection when generating osu-providers.txt. External tools can use
that to configure multiple network profiles for OSU to cover the cases
where transition mode is used.
