selftests/bpf: trace_helpers.c: do not use poisoned type
[ Upstream commit a68b50f47bec8bd6a33b07b7e1562db2553981a7 ]
After commit c698eaebdf47 ("selftests/bpf: trace_helpers.c: Optimize
kallsyms cache") trace_helpers.c now includes libbpf_internal.h, and
thus can no longer use the u32 type (among others) since they are poison
in libbpf_internal.h. Replace u32 with __u32 to fix the following error
when building trace_helpers.c on powerpc:
error: attempt to use poisoned "u32"
Fixes: c698eaebdf47 ("selftests/bpf: trace_helpers.c: Optimize kallsyms cache")
