Fixed portability issues with union sigval.

AIO support in nginx was originally developed against FreeBSD versions 4-6,
where the sival_ptr field was named as sigval_ptr (seemingly by mistake[1]),
which made nginx use the only name available then.  The standard-complaint
name was restored in 2005 (first appeared in FreeBSD 7.0, 2008), retaining
compatibility with previous versions[2][3].  In DragonFly, similar changes
were committed in 2009[4], with backward compatibility recently removed[5].

The change switches to the standard name, retaining compatibility with old
FreeBSD versions.
