[S3] WrapFS does not wrap makepublic method of S3FS

[ms7s]

WrapFS does not wrap makepublic method exposed from S3FS, therefore when used in SubFS, the path is not encoded correctly.

So, for example when I open a directory with S3FS and call makepublic on a file inside it,
the call sets permissions for filename instead of dirname/filename.
