    It may be from Old Norse Þjóstólfr. According to Kruken & Stemshaug, Norsk personnamnleksikon, in Norway this became Tjostolv (literary), with traditional forms Tjøstel, Tjøstol, Tjøstolv, and Tjøstov, but in older sources it is usually written with initial Kj- or sometimes Ky-. They mention specifically Kystolv and Kjøstel.

    The first element is presumably kin to þjóstr ‘anger, fury, vehemence’, and the second is of course the ‘wolf’ word. I don’t see the first element in Lena Peterson’s Nordiskt runamnslexikon, but Landnámabók mentions a Þjóstólfr, son of Björn gullberi, who was one of the original settlers.
