[meta-intel] [PATCH 3/3] lttng-modules: add bbappend to address 3.19.5 update

[Saul Wold]

The 3.19.5 kernel update included an incompatible change that caused lttng-modules
to fail to build, the patch needed to be rebased due to changes in the associated
Makefile.

+lttng-modules: replace KERNELDIR with KERNEL_SRC
+
+Since lttng-modules uses the default way of module.bbclass to
+build and install lttng-modules, we do this replacement for
+it as-is.
