What

Updates the Linux syscall tables in pkg/system to match Linux v7.4-rc1 (6628e7d4c6b2).

• Added syscalls 463-472 to x86_64, x86_32, arm64, and arm32:
  setxattrat, getxattrat, listxattrat, removexattrat, open_tree_attr, file_getattr, file_setattr, listns, rseq_slice_yield, fchroot
• Added the x86_64-only uprobe syscall (336), replacing the old reserved.336 placeholder.
• Bumped Syscall*MaxNum* / Syscall*LastName* constants to 472 / fchroot.

Why

Keep syscall name/number resolution current for seccomp and syscall processing.

How Tested

Compared each generated table against the upstream Linux tables. The only remaining upstream name difference is the pre-existing arm32 syscall 341 alias (sync_file_range2 vs arm_sync_file_range), which was left unchanged intentionally.

What changed in this PR

Updates pkg/system syscall tables for Linux 7.4-rc1, keeping syscall name/number resolution current for seccomp and syscall processing.

Changes:

• Replaces x86_64’s reserved.336 placeholder with uprobe.
• Updates maximum syscall numbers to 472 and last-name constants to fchroot.
