chore(ci): use debug profile for k8s e2e build

[thomasqueirozb]

Summary

The k8s e2e build job was using a release build with optimizations disabled via CARGO_PROFILE_RELEASE_OPT_LEVEL=0 and CARGO_PROFILE_RELEASE_CODEGEN_UNITS=256 as a workaround to get fast compile times. This switches to an actual debug build by making Makefile.packaging and package-deb.sh respect the PROFILE env variable (defaulting to release), and sets PROFILE=debug in the workflow.
