Dockerfile: setup for building libafl_qemu in Docker (#1899)

* fix(Dockerfile): add build_linux.rs to libafl_qemu and libafl_qemu_sys

* fix(Dockerfile): workaround for llvm.sh failing on bookworm

Revert this once llvm/llvm-project#62475 has been resolved

* fix(libafl_qemu): add unsafe to callbacks

* chore(devcontainer): update devcontainer to work with newer VSCode versions

* revert(libafl_qemu): revert unsafe keyword

* fix(devcontainer): move settings and extension under customizations.vscode

* fix(devcontainer): use postCreateCommand instead of initializeCommand
