[PATCH bpf-next] libbpf: fix the use of aligned attribute

[Andrii Nakryiko <andrii@kernel.org>]

Building libbpf sources out of kernel tree (in Github repo) we run into
compilation error due to unknown __aligned attribute. It must be coming
from some kernel header, which is not available to Github sources. Use
explicit __attribute__((aligned(16))) instead.

Fixes: 961632d54163 ("libbpf: Fix dumping non-aligned __int128")
