cmd/compile: use correct (field/method) node for position info

Position info for fields and methods was based on the wrong node
in the new export format, leading to position info for empty
file names and 0 line numbers. Use correct node now.

Due to compact delta encoding, there is no difference in export
format size. In fact, because encoding of "no line changed" is
uncommon and thus a bit more expensive, in many cases the data
is now slightly shorter.

Stats for export data size (pachage, before, after, delta%):
