Facored Class Bonus 1 / 6 rogue talent and Unchained rogue

[Muzouka]

If I use Unchained Rogue does my Kitsune FCB of 1/6 rogue talent convert to 1/6 unchained rogue talent?

Yes

It would also count towards Ninja Tricks for a ninja since the Ninja is a variant Rogue.

Hate to be that guy, but the Ninja Tricks class feature is not the Rogue Talents class feature, and nothing says it counts as Rogue Talents, so no, Favored Class bonuses that refer to Rogue Talents do not apply to Ninja Tricks under the rules. It's a pretty reasonable house rule, but it's not something available in PFS.
