libjitterentropy: add 2.1.2

>From the following kernel commit we know: Fedora has integrated the jitter
entropy daemon to work around slow boot problems, especially on VM's that
don't support virtio-rng

Do the same thing for Yocto.

+SUMMARY = "Hardware RNG based on CPU timing jitter"
+DESCRIPTION = "The Jitter RNG provides a noise source using the CPU execution timing jitter. \
+It does not depend on any system resource other than a high-resolution time \
+stamp. It is a small-scale, yet fast entropy source that is viable in almost \
+all environments and on a lot of CPU architectures."
