fix: Build ubuntu image and use them instead of alpine

[dalehamel]

Fix for #51 and also bumps bpftrace to 0.9.2 from ubuntu eaon

I was able to confirm that the script that doesn't work with static bpftrace works with the dynamically linked one. This is at the expense of a slightly larger (well, 3x larger), though the size here shouldn't matter too much.

As I state in #51, the preferred solution would be to fix the static alpine build (no idea how to do this), or get a static build for ubuntu working (should be possible, others are working on it).

This could at least be a stop-gap until there's a working/non-crashy static image available

Looks like I broke CI with this ,will need to see what's up later (train wifi is garbage).

Testing this out locally and seems to work. My approach was to leave the alpine build, and use dependencies to target which build should actually be done in the makefile. This should allow for keeping the alpine image up to date easily.

I moved all the dockerfiles to the build directory as well.

The commit history is ugly, i'll rebase before merging if the changes are approved.

Assigned to me to continue work:

Tasks:

• pin the bpftrace version on this ubuntu image
• rebase everything
• make sure we ship at least bpftrace 0.9.2
