crfsuite and liblbfgs need their lib folders for electron-rebuild success

[AimForNaN]

In order to be able to use this module in electron it needs to be rebuilt using electron-rebuild. However, because the dependencies do not have their lib directories (which contain all necessary header files, etc), electron-rebuild fails to rebuild node-crfsuite. It would be nice if node-crfsuite shipped with these folders or made where electron-rebuild does not fail.
