lib/oe/path: Add replace_absolute_symlinks function 

We need a function to walk a directory and replace absolute symlinks with
relative ones. Add such a function to the path module of lib/oe.

It does this relative to the directory being walked for files.

(From OE-Core rev: 15376e5ff35367c1b40941d10e7b19302058a53e)
