UBUNTU: [Packaging] add linux-bpf-dev package

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2050083

Add a new binary linux-bpf-dev package that ships a generated vmlinux.h
header. This can be used by packages building CO-RE BPF programs instead
of generating it at build time based on the kernel running on the package
build system, which might or might not match the kernel that is actually
shipped. It ensures that a matching header can always be used.

Matches changes in Debian, including the package name and header installation
location, so that we do not have to ifdef:

https://salsa.debian.org/kernel-team/linux/-/commit/f52d006f3915ac4358dc8c98aa417477ebee026e

This is already used by systemd to build various CO-RE programs, and
right now on Ubuntu due to the lack of this package the header is
generated from sysfs in the build system where the systemd packages are
built.
