## Why
The x32 ABI shares the x86-64 audit architecture, so the architecture check alone does not enforce syscall restrictions for x32 callers.
## What changed
Apply existing syscall denials and socket-family conditions to x32 syscall numbers on x86-64, including separate x32 numbers and legacy aliases supported before Linux 5.4.
## Testing
Add probes across all three network seccomp modes to verify that restricted native and x32 calls return `EPERM`, allowed calls preserve their behavior, and socket-family restrictions apply to both ABIs.
