Note that the vdso is often special, compared to other ELF dsos, because
the loaded part is just the complete ELF image in memory. Since they are
very simple they will just have one PT_LOAD at offset zero and if the
image is smaller than the page size then the whole file is just simply
mapped into memory completely. So by fetching the vdso ELF image from
remote memory you should be able to get the section headers and the
not-allocated sections too.
