replace lttng with lttng-2.0 in core-tools-profile, v2

From: Tom Zanussi <[email protected]>

The current packagegroup-core-tools-profile pulls in 'legacy' lttng packages, which are useless with the linux-yocto kernels since those don't include lttng support.

lttng-2.0 does seem to work, if the patch for lttng-modules that I just sent to oe-core is applied as well (lttng-modules: update SRCREV and remove is_compat_task).

I've only done minimal testing using qemux86, but even so it should at least be better than the curent situation.

Sending this patch to poky instead of oe-core since it could be that legacy lttng is what's being used by most people, but it clearly doesn't work for yocto.

v2: the current lttng2 recipes don't build for mips. From the recipes:

# Due to liburcu not building for MIPS currently this recipe needs to

  # be limited also.
  # So here let us first suppport x86/arm/powerpc platforms now.

NOTE: this patch requires the accompanying oe-core patch to be applied as well:

From: Tom Zanussi <[email protected]>

packagegroup-core-tools-profile currently pulls in the 'legacy' lttng packages, which are useless without legacy lttng support in the kernel.

This makes packagegroup-core-tools-profile pull in the lttng 2.0 packages instead, which don't need any kernel modifications to work.
