sim: formally assume unistd.h always exists (via gnulib)
We have many uses of unistd.h that are unprotected by HAVE_UNISTD_H, so this is more formalizing the reality that we require this header. Since we switched to gnulib, it guarantees that a unistd.h exists for us to include, so we're doubly OK.
