Subject: [PATCH] deps(rustix): enable use-libc to route syscalls through glibc

Without use-libc, rustix uses direct inline assembly syscalls,
bypassing glibc entirely. On a glibc-based system like Debian,
this can break LD_PRELOAD interposition, sanitizers, and miss
glibc optimizations like the getpid() cache.
