Bug#918666: wine hardcodes /run/user/$UID directory

[Julian Andres Klode <jak@debian.org>]

Source: wine
Severity: normal

wine hardcodes the use of /run/user/$UID/wine if it can determine
$UID (if getuid() exists) as the place to store server information.

It's not clear to me who is responsible for creating those directories,
but I'm not sure we can rely on them being available, so wine should
fallback to /tmp if /run/user/$UID does not exist, I guess.

In fact, it should be using $XDG_RUNTIME_DIR, not
hardcoding /run/user/$UID.

(this surfaced in Ubuntu autopkgtest for gpgv-win32).
