[PATCH bpf-next] selftests/bpf: use bootstrap bpftool for core_reloc tests

[Andrii Nakryiko]

Use minimal bootstrap version of bpftool for testing min_core_btf
functionality in core_reloc tests. This avoids unnecessary dependencies
on libbfd, libcap, etc that full bpftool might have in build host
differs from the one in which the test is actually run. This is
currently the case for BPF CI, where build host has libbfd, but stripped
down Linux image inside QEMU doesn't, which causes CI tests to fail.
