Allow changing error action in seccomp filters
Let user specify the action when seccomp filters trigger:
- errno name like EPERM (default) or ENOSYS: return errno and let the process continue.
- 'kill': kill the process as previous versions
The default action is EPERM, but killing can still be specified with
syscall:kill syntax or globally with seccomp-error-action=kill. The
action can be also overridden /etc/firejail/firejail.config file.
Not killing the process weakens Firejail slightly when trying to
contain intrusion, but it may also allow tighter filters if the
only alternative is to allow a system call.
