lttng-tools: sessiond: disable: match app event by name
Get upstream patch from lttng-tools github: <https://github.com/lttng/lttng-tools> <commit:700c5a9d4dc7b552926b8ddcbba91cc13312aba0>, for solving the filtered tracepoint disabling error. The use of a simple lookup and match on event name is insufficient to identify the corresponding ust app event.
