It'd be great to be able to do something like
"${root_gen_dir}/net/{{source_dir}}/{{source_name_part}}-inc.cc"

but that does not appear to be supported.

Ah, here's what you do: Move this action to a new file in
src/net/base/registry_controlled_domains/BUILD.gn. Then replace this line with:
  outputs = [ "$target_gen_dir/{{source_name_part}}-inc.cc" ]
(update the one below as well). Target gen dir is what you're supposed to use
for stuff like this, and it's basically the current build file's path under
out/gen.
