Rename pixel test bug_1021762 to bug_1457.

The original pixel test bug_1021762.in doesn't reflect the original
issue from crbug.com/1021762, but it still reflects a valid rendering
issue. This CL renames bug_1021762.in to bug_1457.in and updated the
expected result and SUPPRESSIONS list accordingly. Another pixel test
will be uploaded for crbug.com/1021762 in a separate CL.
