libbpf source has moved to a separate github repo but keeps the kernel
as the true/first source, and updating github repo when release is ready.
In Steve's word the problem they faced is:

So, looking at libbpf github repo at [1], I can see libbpf has already
released v0.0.6 but we only have v0.0.5 in Debian and there is no way
to update that unless the kernel is updated to v5.5+. And looking at
the kernel repo I can see libbpf people are working on v0.0.7. The full
discussion is at [2].

Do we package libbpf from their github repo independent of the kernel
update? Then we will need to remove the libbpf building bits from the
Debian kernel source and create a separate package for libbpf.
And so, it will be great if kernel team will like to package and maintain
it, if not, then I will be happy to do it. Please reject this bug report
if you think libbpf should not be done separately and should live inside
kernel source package.
