0d3d5d4bcb Seccomp_unotify based monitor
Unotify based monitor should bring big performance wins
if the sandboxee heavily uses threading or signals.
Some of the features are not supported in that mode:
- execveat is always allowed instead of just the initial one
- stack traces are not collected on normal exit or if the process is terminated by signal

cd945565f5 Run more tests with coverage and sanitizers
Running with a permissive test policy should not interfere with sanitizers
or coverage.
Most tests should run with such a permissive policy.
The exception are tests which actually tests policy enforcement.
