Compilation failure for bps.c

Hi, I'm using Ubuntu 22.04 for compling. Already installed dependencies following [INSTALL.md](https://github.com/iovisor/bcc/blob/master/INSTALL.md).

```

With further looking with strace, the files got read for headers that suppose to include `BPF_PROG_TYPE_NETFILTER` and `BPF_MAP_TYPE_ARRAY` is `src/cc/libbpf.h` and in turn `src/cc/libbpf/include/uapi/linux/bpf.h`, it looks like the kernel uapi header itself but not as updated to include the enum value bpc.c requires.

Unclear on if this is a build system issue (so it points to the wrong header) or the header should be updated, so leaving this as a question here. Thanks.

Start with introspection/bps.c and inspect the header resolution through src/cc/libbpf.h to src/cc/libbpf/include/uapi/linux/bpf.h. Compare the missing BPF_PROG_TYPE_NETFILTER and BPF_MAP_TYPE_ARENA definitions with the Ubuntu 22.04 build inputs and INSTALL.md guidance. Done means bps.c compiles successfully with the intended headers.
