tests: stabilize test-extdiff.t on Windows
The test harness only wanted to drop the (windows !) lines, which also means the
actual output matched the (no-windows !) lines. So drop those annotations too.
I suspect if the output of the affected tests was actually collected on Windows,
things were quoted because TEMPDIR contained a `~` in MSYS. Typically that
happens when the username is 9 (8?) or more characters. I explicitly set TEMP
and TMP to something short like "C:\temp" to avoid this, because otherwise there
are a bunch of failures like this in other tests.
