Pat Tullmann 4d6429fc4f POSIX link() syscall only takes two arguments (no flags) ...

The signature is documented as:

   int link(const char *, const char *);

(see https://man7.org/linux/man-pages/man2/link.2.html or https://man.netbsd.org/link.2)

And its not some Linux extension, the [syscall
implementation](21b136cc63/fs/namei.c (L4794-L4797))
only expects two arguments too.

It probably *should* have a flags parameter, but its too late now.

I am a bit surprised that linking glibc or musl against code that invokes
a 'link' with three parameters doesn't fail (at least, I couldn't get any
local test cases to trigger a compile or link error).

The test case in std/posix/test.zig is currently disabled, but if I
manually enable it, it works with this change.
