i386: use socketcall even if newer linux exposes direct syscalls
The changeset 9dea5dc921b5f4045a18c63eb92e84dc274d17eb in the Linux kernel expose the direct syscalls for sockets. For example udhcpc then will use sendto syscall directly and get an EINVAL error. Disable direct syscalls as it was done for SPARC in the past. Musl and GNU libc are not affected, as they already disable direct socket syscalls on i386.
