gstdoc-scangobj: maintain previous XML formatting

Maintain the previous XML formatting, ie. add newlines after each xml item.
Also make sure file does not end with a newline character. Simplify xmlprint()
function a little to not use home-baked xml escaping - there's a GLib function
for that, so we may just as well do it properly.
