Add scalibr os benchmarks

[ganochenkodg]

New test TestScalibrBenchmark to test os/dpkg, os/rpm, os/cos extractors. Sample command to run the test:

sudo go test -v -tags=benchmark -run=TestScalibrBenchmark ./packages/ 2>&1 | grep ' | '

Sample output on debian 13:

Hi @ganochenkodg. Thanks for your PR.

I'm waiting for a GoogleCloudPlatform member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Can we move the code to a dedicated utiltrace package?

[ganochenkodg]

Just checked if it's possible. Unfortunately, no:

1. Circular import dependency. The packages package already imports github.com/GoogleCloudPlatform/osconfig/util/utiltrace (in trace.go). So import packages in util/utiltrace/ produces an error - import cycle not allowed
2. The benchmark relies on scalibrInstalledPackagesProvider, which is an unexported struct defined inside the packages package and cannot be accessed outside of it without code refactoring
