libbpf: Implement basic zip archive parsing support

Browse source

This change implements support for reading zip archives, including
opening an archive, finding an entry based on its path and name in it,
and closing it.
The code was copied from https://github.com/iovisor/bcc/pull/4440, which
implements similar functionality for bcc. The author confirmed that he
is fine with this usage and the corresponding relicensing. I adjusted it
to adhere to libbpf coding standards.
