Fix BackSpace not working in Find box.

This regressed with:
http://codereview.chromium.org/99161

I think more work is needed, such as:

1) Figure out if more combinations need to be added.
2) Figure out if we can consolidate the code into
   one function, so that we don't need to keep three
   ShouldLookupAccelerators in sync (one in TextField,
   one in LocationBarView and potentially one in
   AutocompleteEditViewWin as well (OnKeyDownOnlyWritable).

I'm not sure what all those magic keyboard constants like 
0xBB do, so I think I'll leave the rest of the work to the
person who created the changelist noted above.

BUG=11326
TEST=Open google.com, press About link, press Ctrl+F,
     press e, press BackSpace. Chrome should not navigate
     back.
