lttng-modules: update to 2.5.0
During the uprev of the yocto kernel to 3.16, lttng-modules failed to build. To grab the latest stable content, we update to 2.5.0, and add two patches to also make it build against 3.16+. We also drop the older 2.3.3 lttng-modules, since it is no longer required to support ARM builds.
