ZTS: adjust zpool_import_012_pos timeout

When running in the CI the zpool_import_012_pos test case occasionally
takes longer than the maximum 600 seconds.  When this happens the test
case is considered to have failed but always completes a few minutes
latter.  Since the logs suggest nothing has actually failed this commit
increases timeout and removes the exception.
