Do not use a shared kakoune/ directory for all users to avoid the complexity of having to set the sticky bit on that dir, resolve the session directoy only once by using a static variable and an immediately evaluated lambda. This fixes an annoyance whenver using `su` and having Kakoune refuse to start due to XDG_RUNTIME_DIR still being set.
