[COMMITTED] Fix wake-up in sysdeps/nptl/fork.c.

[Torvald Riegel]

Committed this as obvious.  The futex wake-up needs the address of the
futex variable, not the value.  I've searched glibc bugs for "fork", but
didn't see a bug that seemed to be likely to be related to this.

        * sysdeps/nptl/fork.c (__libc_fork): Provide address of futex
        variable to lll_futex_wake call, not the value itself.
