xdg-user-dirs: check for existing symlink

Browse source 
When a non-directory, such as a file or a dead symlink, already exists,
mkdir -p fails with "cannot create directory ‘...’: File exists".

This is a problem when, for example, a symlink points to a directory on
a filesystem that isn't mounted yet.
