bpftrace-compiler: add vendoring

[christoph-zededa]

Description

hopefully this helps against flakiness of the CI as we experience sometimes the following error:

27 [bpftrace 16/17] RUN CGO_ENABLED=0 GOARCH=${TARGETARCH} go build -o /bpftrace-helper

coverage: 26.6% of statements
panic: test timed out after 5h0m0s

@christoph-zededa , go-tests passed. Is this a good indication that it works? Can we mark the PR as ready for review?

I also added the vendor files for bptrace-compiler, not only the tool that is used by bpftrace-compiler.
It is an indication that it works.
Marked it as "Ready for Review" now.
