containerd: disable custom fuzzers

[austinvazquez]

Related to containerd/containerd/issues/12007

This change disables the custom fuzzers from github.com/AdamKorcz/instrumentation

This is to unblock changes in the containerd release/1.7 branch where the Go toolchain is older than the minimum requirement for the fuzzers in AdamKorcz/instrumentation.

You need to remove these lines upstream first:

@AdamKorcz, I opened containerd/containerd#12059

I am thinking maybe we can pull the instrumentation repo if it does not exist and in the release/1.7 branch pin to a known good version pre-containerd 2.0 module or the Go mod version bump.

Sounds good. I can also update the instrumentation library, however, for getting the upstream CI running, I would just remove it for now.
