Remove support for the Solaris IOCP socket engine.

After discussing this with Adam we have decided that there is very
little point in keeping this now that Solaris has been killed. Any
legacy Solaris users will have to make do with poll.

This change does not affect users of Solaris forks like Illumos as
they have support for epoll which will have already been selected
over Solaris IOCP by configure.
