Currently, when `MOZ_PROFILER_SHUTDOWN` is set to a path that includes directories which don't exist, the profiler fails because of the non-existent directories. It would be useful if the profiler could create those directories. This would make it easier to handle the profile paths in our test harnesses (potentially save us from duplicating code too).

In mochitest, when we're profiling, and the directory doesn't exist we see this error and then the browser hangs:
