lttng-tools: update to version 2.5.0

Update to latest stable-2.5 revision.

* Drop Fix-alignment-problems-on-targets-not-supporting-una.patch, merged
  upstream.
* New build-dependency on libxml2, so inherit pkgconfig so the test works and
  delete the copy of libxml.m4 that overrides our sysroot.

Based on a patch from Yasir-Khan <yasir_khan@mentor.com>.

-
-Accessing floats, doubles and 64 bit int at unaligned addresses is not
-supported on all configurations of arm processors and if it is it's
-emulated and slow. This patch replaces direct assignments with memcpy.
