lttng2: Fix build error related to trace_rcu.
This is the fix for following build error:
ovp-kvm/bitbake_build/tmp/work/intel_x86_64-wrs-linux/linux-windriver/3.10-r
| void trace_##_name(_proto);
rcutree.c defines the argument passed to trace_rcu_utilization to be TPS(x)
which is of type "const char *" while TRACE_EVENT for rcu_utilization
defines the argument to be "char *), so there is a conflicting types for
trace_rcu_utilization

Configure a LPP with the following configure line:
/WRL6_CGP/wrlinux-6/wrlinux/configure --enable-board=qemumips64 --enable-build=profiling --enable-ccache=yes --enable-checkout-all-layers=yes --enable-jobs=3 --enable-kernel=standard --enable-parallel-pkgbuilds=3 --enable-rm-oldimgs=yes --enable-rootfs=glibc_small+debug --with-layer=/WRL6_CGP/wrlinux-6/layers/examples/lemon_layer --with-sstate-dir=/wrl_cache --with-template=feature/demo,feature/code_coverage,feature/analysis,feature/gdb,feature/lttng2,feature/lttng-init
Perform a make fs and observe build failure. (x86-64 + glibc_std also shows failure.
