Kernel: Add KLexicalPath::try_join and use it

Browse source 
This adds KLexicalPath::try_join(). As this cannot be done without
allocation, it uses KString and can fail. This patch also uses it at one
place. All the other cases of String::formatted("{}/{}", ...) currently
rely on the return value being a String, which means they cannot easily
be converted to use the new API.
