Currently benchmark CI step is disabled. Turn it on with following changes: * Use berserker instread of hackbench * Use regular ttest instead of IQR * Compare CPU/Memory usage instead of hackbench time
Adjust reporting for new format, plus add reset command for cleaning up the baseline if needed.
Add systemtap into the builder to allow defining USDT, and add one to capture events when a new process was discovered.
USDT support requires systemtap, but Konflux setup doesn't use the builder image. Add the dependency directly.

Description
This PR adds a new benchmark test that will analyse the syscall latency of a system with and without collector running. It does this by running a program which repeatedly opens, reads, and closes a file. Those syscalls were chosen in order to capture syscalls that Collector is both interested in (close) and not interested in (read)
Having captured the logs, the benchmark will process the data into json, storing a basic analysis (p90, median, mean) alongside the raw data.
