React to restriction of pass-through ::Any Base methods by explicitly implementing replacements

This doesn't affect anything that was already explicitly implemented in FilePathsBase, but would affect things like uperm which used to implicitly work by dispatching to stat, but now will throw MethodErrors. Probably those things should just be reimplemented here.

Just wanted to flag this as I saw it, this might be too soon.

Thanks, seems reasonable. I've started watching that PR and whenever it's ready to be merged I'll run the tests on that branch.
