[oe-core][PATCHv7 1/6] libx11: create tmpfile dir for x11 domain socket

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

Register a volatile directory entry for the x11 domain socket when not
using systemd. This will make sure the directory is always created with
the correct permissions. Systemd already provides their own tmpfile.d
entry for the same behavior.

Currently some x11 related applications will create this directory if it
doesn't already exist, but this is not true for everything. In addition,
if the application in question isn't started as root, it's possible this
directory can be owned by a non-root user. This isn't an issue by
itself, but it can potentially lead to problems in a multi-user
environment.
