This PR is based off [@kakkoyun's work](parca-dev#326) to use libbpf(go)'s batch APIs. **Context** The main issue we found while working with this API was that they were erroring with `EPERM`. After some debugging, we realised that libbpf wasn't handle with errors in the way we expected. The debugging write-up and more context can be found [here](aquasecurity/libbpfgo#159), and the fix is in [this PR](aquasecurity/libbpfgo#157). After landing these changes upstream, we pointed to the updated libbpfgo version, as well as added some [regression tests](parca-dev#381) to ensure that libbpfgo behaves as expected, and to make it easier in the future to write further compatibility tests. Note: the rest of the batch APIs error handling is still unfixed. Tracking in aquasecurity/libbpfgo#162.
