net: socket: add __sys_accept4() helper; remove in-kernel call to syscall

Using the net-internal helper __sys_accept4() allows us to avoid the
internal calls to the sys_accept4() syscall.

This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see
