Create directory for shell<>perfetto interaction
Users are unable to pass config files directly to
perfetto via `perfetto -c /path/to/config` and have to
resort to awkward quirks like `cat config | perfetto -c -'.
This is because /system/bin/perfetto runs in its own SELinux
domain for reasons explained in the bug.
This causes problem to test infrastructures authors. Instead
of allowing the use of /data/local/tmp which is too ill-scoped
we create a dedicated folder and allow only shell and perfetto
to operate on it.
Bug: 170404111
Test: manual, see aosp/1459023
