ci: Enable conformance tests related to 32-bit jumps

Now that rbpf supports 32-bit jump instructions, we can enable the
related conformance tests in the CI. We can also update the container
image to its latest version, in order to pull the fixes from
https://github.com/Alan-Jowett/bpf_conformance/pull/53. All tests should
pass, we already have identical tests in rbpf's suite.
