bpf: Fix test_obj_id.c for llvm 5.0
llvm 5.0 does not like the section name and the function name to be the same: clang -I. -I./include/uapi -I../../../include/uapi \ -I../../../../samples/bpf/ \ -Wno-compare-distinct-pointer-types \ -O2 -target bpf -c \ linux/tools/testing/selftests/bpf/test_obj_id.c -o \ linux/tools/testing/selftests/bpf/test_obj_id.o fatal error: error in backend: 'test_prog_id' label emitted multiple times to assembly file clang-5.0: error: clang frontend command failed with exit code 70 (use -v to see invocation) clang version 5.0.0 (trunk 304326) (llvm/trunk 304329) This patch makes changes to the section name and the function name.
