multitenant: Increase timeout for kvtenantccl

The new TestTenantUpgradeInterlock test takes a long time to run (up to a
minute locally) and has started timing (the first instance being in a
post-merge arm64 test). On the suspicion that it's timing out strictly
because it's long running, increase the timeout to see if that resolves
the failures.

Release note: None
Epic: None
Fixes: #98986
