[oe] [meta-oe][PATCH 1/3] udev: make the dev cache work with /dev/shm

[Andrea Adami]

* At this point in the boot process we may not have a writable /tmp
* directory.  We will have a writable /dev/shm and the data we need
* is small enough that we use this directory.
*
* Patch was committed in the openembedded git server with commit id
* ca688dd2de58dbec865ac7e70fab4d2c373ad822
