we don't need unveil "x" in listener
...
not a big deal, since the pledge prohibits us to exec, but
nevertheless.

allow clock_gettime and a bit of fmt
...
alpine on amd64 (under OpenBSD vmd) tries to do a clock_gettime. I
don't know why, but it doesn't seem a problem to allow it.

[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.
