Daniel Müller 6cb9430be1 libbpf: Ignore warnings about "inefficient alignment" 
Some consumers of libbpf compile the code base with different warnings
enabled. In a report for perf, for example, -Wpacked was set which
caused warnings about "inefficient alignment" to be emitted on a subset
of supported architectures.

With this change we silence specifically those warnings, as we intentionally
worked with packed structs.

This is a similar resolution as in b2f10cd4e8 ("perf cpumap: Fix alignment
for masks in event encoding").

Fixes: 1eebcb6063 ("libbpf: Implement basic zip archive parsing support")
