Fix binary scan SimpleJson tests - change errorExpected from true to false

Root cause: Tests had errorExpected=true, causing assert.Error(t, err)
to be called, which produces no JSON output. This led to 'unexpected
end of JSON input' errors when trying to validate results.

Docker scan tests (which pass) don't use errorExpected - they just
run scans and validate output. Binary scan tests should do the same.

Fixed tests:
- TestXrayBinaryScanSimpleJson (line 103): true → false
- TestXrayBinaryScanSimpleJsonWithProgress (line 172): true → false

These tests create policies/watches and expect successful scans with
violations, not errors. Now they will:
1. Run scan successfully (no error assertion)
2. Get valid SimpleJson output with violations
3. Successfully validate the results
