pe: tighten validity checks of DOS and PE headers

Let's make sure we validate that the DOS/PE header offsets are actually
reasonable, and do not cause overflows when added to the base addresses.

(This shouldn're really be a problem URL, since the DOS header offset is
16bit only, but let's be extra careful with this)
