syscall.c: Fix build with older linux-headers
In
c5dff280 we tried to make us understand netlink messages more.
So we've added a code that does some translation. However, the
code assumed linux-headers to be at least version 4.4 of it
because most of the symbols there (if not all of them) were added
in just that release. This, however, breaks build on systems with
older versions of the package.
