aya: support both bpf_map_def layout variants 
Libbpf and iproute2 use two slightly different `bpf_map_def` layouts. This change implements support for loading both.

Alessandro Decina 4222b140ec aya: perf_map: fix bug when max_entries=0 
When a perf map has max_entries=0, max_entries is dynamically set at
load time to the number of possible cpus as reported by
/sys/devices/system/cpu/possible.

This change fixes a bug where instead of setting max_entries to the
number of possible cpus, we were setting it to the cpu index of the last
possible cpu.

Alessandro Decina 30d2b25f11 aya: xdp: fix detaching on kernels older than 5.7 
XDP_FLAGS_REPLACE was added in 5.7. Now for kernels >= 5.7 whenever we
detach an XDP program we pass along the program fd we expect to be
detaching. For older kernels, we just detach whatever is attached, which
is not great but it's the way the API worked pre XDP_FLAGS_REPLACE.

Add a `target_btf: Option<Btf>` argument to Bpf::load. None can be

don't support it. Some(btf) can be used to pass BTF parsed with
Btf::from_sys_fs() or Btf::parse/parse_file.

Finally, add a simpler Bpf::load_file(path) that uses from_sys_fs()
internally to simplify the common case.
