Remove references to nonexistent runtime/include/threads/... paths.

(Reviewed by @ronawho.)

In a few places our Makefiles were throwing target compiler '-I' options
referencing runtime/include/threads/... paths that existed at one time
but aren't present any more. I believe these include paths were removed
in Split bundled and system -I and -L arguments by mppf · Pull Request #18880 · chapel-lang/chapel · GitHub, and these refs were
missed just because they were partly built out of make(1) variable
values.
