Subject: libbpf: Fix the use of aligned attribute
Patch-mainline: v5.16-rc1
Git-commit: fae1b05e6f0acf116f6450535b0e1c13051102d3
References: jsc#PED-1377

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")
