Update ruby-ole to 1.2.11.2.

== 1.2.11.2 / 2011-09-07

- Remove empty dirents after constructing tree (fixes non-contiguous
  allocation table usage).
- Fix fallback Symbol#to_proc to match activesupport definition in case
  we get loaded first (github #2, lazylester).
- Use method_defined? for fallback guards to support newer versions of
  ruby (jocker).
- Add guard on FileTime#initialize to skip for newer versions of ruby.
  Missing required methods, but optimization no longer relevant
  anyway (github #4, sagmor).
