image/populate_sdk: Ensure symlinks in target sysroot are relative
In the target sysroot of an SDK we can have target system absolute links which don't make sense. This adds a script which fixes them up to become relative paths instead. [YOCTO #5020] Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
