When writing out current PE contents only write data
up to `sectionTable.offsetEnd` because that is the
offset used to compute location of the snapshot
section and there might be a padding between
`offsetEnd` and the actual end of the file.
This was revealed when compiling AOT runtime
with ASAN enabled which slightly shifted
sections in the PE file and introduced
a gap.
TEST=manually internally
