Camera: Skip testZoomTimestampIncrease if firstApiLevel < V

- Use firstApiLevel because 24Q2 build bumps up vendor API level
  to 202404.
- Vendor API level is not visible to app developers anyway. So
  there is no way for app developers to gate behaviors based on
  the vendor API level.

Test: atest CaptureRequestTest#testZoomTimestampIncrease
