[PATCH bpf-next] bpf: Fix cold build of test_progs-no_alu32

[Brendan Jackman]

This object lives inside the trunner output dir,
i.e. tools/testing/selftests/bpf/no_alu32/btf_data.o

At some point it gets copied into the parent directory during another
part of the build, but that doesn't happen when building
test_progs-no_alu32 from clean.
