Show chocobo warning in non-city outposts

Outposts like Summerford Farms in the open world are considered Sanctuaries. But chocobos can be summoned and the timer continues to tick down. This change shows the chocobo warning in outposts so that it can be refreshed before the chocobo buff is lost.

Checking if the buddy is alive is a bit too hacky for my tastes.

Instead I check if you are able to use Gysahl Greens while in a sanctuary.

If you check for Gysahl Greens, the warning wouldn't show up while mounted within outposts because you can't use items while mounted. It would have a different behavior than when you're mounted outside outposts where the warning would be shown even while mounted.

You are correct, you can't use items while mounted. That's not what my function is checking for at all.
