importccl: disable automatic stats for TestImportCSVStmt

TestImportCSVStmt tests that IMPORT jobs appear in a certain order
in the system.jobs table. Automatic statistics were causing this
test to be flaky since CreateStats jobs were present in the jobs
table as well, in an unpredictable order. This commit disables
automatic stats for this test.

Fixes cockroachdb#34568

Release note: None
