Now that bpf-linker uses llvm 16, the easiest way is to use Fedora 38
Beta with the testing repos as they have it, without resorting to
Rawhide.
See https://packages.fedoraproject.org/pkgs/llvm/llvm/.
This commit adds from_pin() which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.
This differs from #444 since it implements this on the concrete program
type, not the Program enum, allowing the user to pass in any additional
context that isn't available from bpf_prog_info.

Before this chane, the check was always negative if the minor version
was less then 9. So, for example, the smoke test was skipped for kernel
6.1:
```
skipping as 6.1 does not meet version requirement of 5.9
```

Simplifiy the relocation tests build process by removing the need for libbpf
at runtime. Its usage is replaced with local `__builtin_*` attributes.
This removes the need for the `LIBBPF_INCLUDE` env variable.
This commit adds documentation on how program names are parsed from
section names, as is used by `aya_obj::Object.programs` as HashMap keys,
and updates the examples into using program names.
Instead of returning anyhow>>Result<()> handle errors
'in-place' with unwrap or panic, for more informative
and user-friendly error messages on test failures.
Fixes#421.

switch map() and map_mut() from returning a
`Result` to an `Option` since it's just getting
a value from a Hashmap, and to stay in line with
the Programs API.
Remove `MapError::MapNotFound`

Build completing tests passing
Refactor the Map API to better align
with the aya programs API. Specifically
remove all internal locking mechanisms
and custom Deref/DerefMut implementations.
They are replaced with a Map enum
and AsRef/AsMut implementations.
All Try_From implementations have been moved
to standardized enums, with a slightly
special one for PerfEventArray's.
Also cleanup/fix all associated tests and
documentation.

We often need to wait a bit until the program or link gets unloaded
after dropping.
Also, using a macro makes it clear in which particular test the panic
happened.

libbpf 1.0 doesn't support multimaps defined in `maps` section, it
supports only BTF maps.
At the same time, we already test multimaps loading with the Rust
example (`integration-ebpf/src/bpf/map_test.rs`), so we can just remove
the failing C test.
