backend: unify NewFs path handling for wrapping remotes
Use the same function to join the root paths for the wrapping remotes alias, cache and crypt. The new function fspath.JoinRootPath is equivalent to path.Join, but if the first non empty element starts with "//", this is preserved to allow Windows network path to be used in these remotes.
