[seccomp] allow also poll
on the latest fedora we glibc uses poll. On the other linux distro I tried (void), musl is probably providing poll as a ppoll wrapper.
split into two processes: listener and executor
this way, we can sandbox the listener with seccomp (todo) or capsicum (already done) and still have CGI scripts. When we want to exec, we tell the executor what to do, the executor executes the scripts and send the fd backt to the listener.
