TCP and UDP get_sock_opt/set_sock_opt had duplicate match arms
due to constant collisions (Linux-level values share namespace):
TCP: TCP_MAXSEG=2, IP_TTL=2, SO_REUSEADDR=2 → kept TCP_MAXSEG
UDP: IP_TTL=2, SO_REUSEADDR=2 → kept IP_TTL (more useful)
Removed unreachable arms with explanatory comments. The
collision is inherent — Linux uses different option levels
(SOL_SOCKET vs IPPROTO_TCP vs IPPROTO_IP) but Redox scheme
has a flat namespace. Applications that use multi-level
getsockopt() would need richer level dispatching.
