Increase bpf stack size and add -g to pass compilation
Error1: external/bcc/libbpf-tools/runqlat.bpf.c:88:17: error: using builtin_preserve_access_index() without -g
Error2: external/bcc/libbpf-tools/cpudist.bpf.c:70:3: error: Looks like the BPF stack limit is exceeded. Please move large on stack variables into BPF per-cpu array map. For non-kernel uses, the stack can be increased using -mllvm -bpf-stack-size.
Bug: b/308826679
