As the Linux semop syscall is not defined in i386, and as it is equal
to the native semop syscall, call it directly.
Fix semop definition to match Linux actual one - nsops is size_t type.

On Linux, this syscall doesn't take any arguments; instead
it assumes the context was put on the stack.

Linux/arm64 is CLONE_BACKWARDS - i.e., "Architecture has tls passed as
the 4th argument of clone(2), not the 5th one."
The linux clone() syscall has four different permutations of argument
order, depending on architecture - see the #ifdef CONFIG_CLONE_BACKWARDS
maze in Linux's kernel/fork.c.
