[PATCH] tracetool-test: allow to run in parallel

[PATCH] tracetool-test: allow to run in parallel

[marcandre.lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Create a temporary build subdirectory, to avoid conflicting with other
running tests. This fixes "meson test" with tracetool-test which is
parallel default.
