bpf: Use option "help" in the llvm-objcopy test
I noticed the "--version" option of the llvm-objcopy command has recently disappeared from the master llvm branch. It is currently used as a BTF support test in tools/testing/selftests/bpf/Makefile. This patch replaces it with "--help" which should be less error prone in the future.
