Introduced at merge commit dca722ec7b2a7fc9214844ec92310074b5cb2faa.

We just want to ignore the warning.

valgrind: ignore lttng warning on un-cleaned-up state

This appears to have come from dca722ec7b2a7fc9214844ec92310074b5cb2faa,
which merged in support for use of lttng ust functions on fork. Valgrind
started warning on a Leak_StillReachable with lttng_ust_init in
the function call trace.

Hopefully this is specific enough that we don't mask out any other
lttng errors.
