Dave Tucker 9426f36f79 Implement Pinning For Programs and Maps
This commit adds 2 new methods to aya::sys
- bpf_pin_object
- bpf_get_object

Which allow the pinning and retrieval of programs/maps to bpffs.

It adds a `Program.pin` API, such that a loaded program can be pinned.
For map pinning, the user must ensure the `pinning u32` in the
`bpf_map_def` is set to 1, maps will be pinned using a new builder API.

BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o")

This will pin all maps whose definition requests pinning to path + name.

Fix rustup command in the docs. (#48)
rustup install nightly --component rust-src

gives:

```
error: Found argument '--component' which wasn't expected, or isn't valid in this context

USAGE:
    rustup install [FLAGS] [OPTIONS] <toolchain>...

For more information try --help
```

The correct command seems to be `rustup toolchain install nightly --component rust-src`.

Alessandro Decina c2a90c2c01 aya: tc: add qdisc_detach_program
qdisc_detach_program can be used to detach all the programs that have
the given name. It's useful when you want to detach programs that were
attached by some other process (eg. iproute2), or when you want to
detach programs that were previously left attached because the program
that attached them was killed.
