test-revert-interactive: don't escape the $ for $TESTTMP

Otherwise, sh tries to exec the literal path '${TESTTMP}/editor.sh' on Windows.
The test runs clean on OS X both with and without this change.

 Check editing files newly added by a revert
 
 1) Create a dummy editor changing 1 to 42
   $ cat > $TESTTMP/editor.sh << '__EOF__'
   > cat "$1"  | sed "s/1/42/g"  > tt
   > mv tt  "$1"
   > __EOF__
 
 2) Remove f
   $ hg rm f
   $ hg commit -m "remove f"
 
 3) Do another commit on top
   $ touch k; hg add k
   $ hg commit -m "add k"
   $ hg st
 
 4) Use interactive revert to recover f and change it on the fly
