Don't use FS

[jods4]

From @niieani

a potential problem: you are requiring the Node fs module, which is incorrect for any Webpack plugins or loaders. The reason is filesystems can be replaced/mocked by Webpack in certain conditions and make it dynamic or in-memory, and Webpack provides an interface to use the internal fs module, available to the loaders and plugins

Fixed, now both ExtensionsDependenciesPlugin and GlobDependenciesPlugin probe the compilation.inputFileSystem instead of fs directly.

Nice one. 👍
