selftests/bpf: Temporarily disable part of btf_dump:var_data test.

Commit 7443b29 ("x86/percpu: Move cpu_number next to current_task") moved global per_cpu variable 'cpu_number' into pcpu_hot structure. Therefore this part of var_data test is no longer valid. Disable it until better solution is found. Signed-off-by: Alexei Starovoitov <ast@kernel.org>
