lttng-modules: update to 2.5.0

Browse Source 
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.

(From OE-Core rev: 10680c8f06c52b25ed63d315596707701402646d)
