Subject: libbpf: Fix usage of u32 in userspace code
Patch-mainline: v5.5-rc1
Git-commit: b615e5a1e067dcb327482d1af7463268b89b1629
References: bsc#1155518

u32 is not defined for libbpf when compiled outside of kernel sources (e.g.,
in Github projection). Use __u32 instead.

Fixes: b8c54ea455dc ("libbpf: Add support to attach to fentry/fexit tracing progs")
