Another attempt to remediate user namespace issues with ubuntu24 runners (pixie-io#2010)

Summary: Another attempt to remediate user namespace issues with ubuntu
24.04 runners

This reverts the failed previous attempt and re-enables user namespaces
on ubuntu 24.04. This is a well known behavior change between Ubuntu
22.04 and 24.04
(actions/runner-images#10443 (comment)).
Since podman is running rootless, I think it's possible that the user
namespace creation (clone syscall) is failing.

Relevant Issues: pixie-io#1993

Type of change: /kind bugfix

Test Plan: Run another production release build after merging this
- Verified that this sysctl cli invocation is similar to our [existing
example](https://github.com/pixie-io/pixie/blob/aa1f72a69f0a072d97accd721081f89cb8108fd1/.github/workflows/build_and_test.yaml#L87)
