Andreas Kling cca5a6dd37 ImageDecoder: Sandbox the process on Linux
Add --enable-sandbox to Ladybird and test-web, pass it through to
ImageDecoder, and make ImageDecoder install its Linux sandbox only when
the option is present.

The Linux implementation enables no_new_privs, configures glibc malloc
to avoid late CPU-count probes in helper threads, applies an empty
Landlock ruleset when available, and installs a seccomp filter for the
helper IPC, shared memory, threading, and decoding syscalls.

Deny plain read-only filesystem probes without granting file access, so
common runtime feature checks can observe the sandbox instead of
terminating the helper during normal decoding.
