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) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
