test-check-help: fix to work on Windows
The initial problem was `hg files` prints paths with '\', which gets removed
when piped (scanhelptopics.py failed to open 'hgext__init__.py'). Then, xargs
was invoking `hg help` with 'backout\r (esc)', which setting binary mode
prevents.

Check if ":hg:`help TOPIC`" is valid:
(use "xargs -n1 -t" to see which help commands are executed)
