fs-util: add chase_symlinks_prefix() and extend comments
chase_symlinks() currently expects a fully qualified, absolute path, relative
to the host's root as first argument. Which is useful in many ways, and similar
to the paths unlink(), rename(), open(), … expect. Sometimes it's however
useful to first prefix the specified path with the specified root directory.
Add a new call chase_symlinks_prefix() for this, that is a simple wrapper.
