[Pkg-rust-maintainers] Bug#1096249: rust-ntp-os-clock: FTBFS: unsatisfiable build-dependencies: librust-rustls-native-certs-0.7+default-dev, librust-rustls-pemfile-2+default-dev

[Peter Green]

I fixed the dependency installability issues with librust-ntp-proto-dev but
rust-ntp-os-clock seems to be incompatible with the new version of
ntp-proto and also seems to be abandoned upstream and has no rdeps
in Debian.

sylvestre, should we remove it?
