[ELF] Fix out-of-bounds write in memset(&Out::first, ...)

Fix r285764: there is no guarantee that Out::first is placed before other
static data members of `struct Out`. After `bufferStart` was introduced, this
out-of-bounds write is destined in many compilers. It is likely benign, though.

And move `Out::elfHeader->size` assignment beside `Out::elfHeader->sectionIndex`
