Disable canonicalization in ccselect tests

DNS canonicalization can interfere with the fallback tests by changing
"localhost" to have multiple components, or (less likely) changing the
parent domain of foo.krbtest.com or foo.krbtest2.com.

(cherry picked from commit b5457d8fb719a583b89e1ace186301a144e2c4c9)
