Load probes from the image

[erthalion]

Teach Collector to load probes located inside the image. Here we don't have to
bother what type of probe is that yet, e.g. for testing it could be a regular
eBPF probe. The path for searching could be fixed, and later on aligned with CI
changes.

Part of #1011

#1040 should make it easier to load drivers from within the image, as well as mix and match driver types which will be needed to fallback to regular eBPF if the new probe fails.

Remaining work for this issue has already been address in #1053
