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 b2f10cd4e805 ("perf cpumap: Fix alignment
for masks in event encoding").
Fixes: 1eebcb60633f ("libbpf: Implement basic zip archive parsing support")
