RFS: new package ceccomp

[Ma Rocket <ma2014119@outlook.com>]

Hello Debian packaging team,

I am working on a new package ceccomp, a C implementation inspired by seccomp-tools.
Related information is already available on the BTS (ITP and general RFS):

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1116186
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1116471

For context: in Capture-The-Flag (CTF) challenges and security environments, seccomp
filters are a common technique to restrict syscalls. Currently users usually rely on seccomp-tools,
a Ruby-based utility that is not packaged in Debian. The ceccomp package provides a modern,
C-written alternative with extended features, and would allow users to set up hacking/CTF
environments more easily via the Debian archive.

I would highly appreciate it if someone could review my package.
If this package is accepted, I would also like to join the pkg-security team to maintain it.

Thanks in advance for your review and feedback.

Best regards,
Rocket Ma
