Subject: [PATCH] Suppress useless warnings during udev startup

I have a number of platforms which have no realtime clock
(i.e. no sense of what day/time it is).  On these platforms,
poky dutifully tries to keep somewhat sane with stored
time stamps that are saved on reboot and restored early
on during initialization.  A fair compromise.

However, before that code runs, the udev script tries to
restore well known devices using tar.  This will often
lead to messages such as these since the kernel has no
way to set the time:
   tar: dev/pts: implausibly old time stamp 1970-01-01 00:00:00
   tar: dev/char/3:134: time stamp 1970-01-01 00:00:09 is 0.435041705 s in the future

The attached patch filters these messages out as they don't
convey anything useful and indeed are worrisome to more naive
users.
