Weston should fallback if XDG_RUNTIME_DIR is not set as per the XDG specification

[Fred .]

I believe Steve Langasek (vorlon) who updated mountall from 2.38 to
2.40 in Ubuntu (which added preliminary support for XDG_RUNTIME_DIR)
is also working
on the PAM module (the second half of XDG_RUNTIME_DIR support).

So hopefully we will see Ubuntu have XDG_RUNTIME_DIR support soon.
