base: fix creation of msg queues [#3107]
Message queues stop working correctly after queue file is removed from /tmp.
Message queue API uses "ftok" which relies on the file being permanent. The
behaviour is undefined if the file is removed. Many systems clean out /tmp
periodically, so this can break if the message queue is long lived.
Create the queue file in /var/run.

Your checkin has not passed review because (see checked entries):

___ You have exceeded a sensible line length in your headers/comments/text.

___ You have incorrectly put/left internal data in your comments/files
(i.e. internal bug tracking tool IDs, product names etc)
___ You have not given any evidence of testing beyond basic build tests.
Demonstrate some level of runtime or other sanity testing.
___ You have ^M present in some of your files. These have to be removed.
___ You have needlessly changed whitespace or added whitespace crimes
like trailing spaces, or spaces before tabs.

___ You need to refactor your submission into logical chunks; there is
too much content into a single commit.
___ You have extraneous garbage in your review (merge commits etc)
___ You have giant attachments which should never have been sent;
Instead you should place your content in a public tree to be pulled.

commits, or place in a public tree for a pull.
___ You have resent this content multiple times without a clear indication
of what has changed between each re-send.
___ You have failed to adequately and individually address all of the
comments and change requests that were proposed in the initial review.
___ You have a misconfigured ~/.gitconfig file (i.e. user.name, user.email etc)
