unix: update to use direct linking on Solaris

CL 9184 changed the runtime and syscall packages to link Solaris binaries
directly instead of using dlopen/dlsym but failed to update sys/unix to
reflect these changes.  This changes the Solaris port to use direct linking
as supported by Go 1.5.

Fixes golang/go#10086
