Each thread may have a specific context in the trace2 subsystem that we
set up via thread-local storage. We do not set up a destructor for this
data though, which means that the context data will leak.
Plug this leak by installing a destructor. This leak is exposed by
t7814, but plugging it alone does not make the whole test suite pass.
