test-rebase-interruptions: stabilize for Windows

External hooks end up launching cmd.exe, which knows nothing about $VAR syntax.
For some reason, I thought that Mercurial would substitute in the value, in
order to paper over the platform difference.  But I can't find that in the
documentation, and there's at least one other use of this pattern [1].
