ci(libscap): Run libscap fuzzer in CI

[tks98]

What type of PR is this?

/kind test

Any specific area of the project related to this PR?

/area libscap
/area tests

Does this PR require a change in the driver versions?

No.

What this PR does / why we need it:

This follows up on #2857 by running the libscap fuzzer using the synthetic corpus only for 15 seconds for simplicity.

The idea would be that a long running fuzz job would be added to oss-fuzz and this would just validate functionality and severe regressions.

I was able to test this CI stage using act locally to try to validate it works as close as I could to actual GitHub actions but can make any changes required once it's actually run here.

act pull_request -j libscap-fuzz-smoke \
  --container-architecture linux/amd64 \
  -P ubuntu-24.04=catthehacker/ubuntu:act-24.04

Does this PR introduce a user-facing change?:

NONE
