[oe] [meta-oe][PATCH 2/3] udev: Fix cache problem

[Andrea Adami]

* When /dev/shm is re-mounted we need to re-create the files that end up
* in /etc/udev/saved.*.  In addition, udev 124 wasn't making an initial
* saved.uname file.
*
* Patch was committed in the openembedded git server with commit id
* b6838a476a9c448cd994634688ead0815226b9fe
