aya/maps: fix libbpf_pin_by_name, add pin() api

- Aligns with libbpf for the special LIBBPF_PIN_BY_NAME
map flag. Specifically if the flag is provided without a pin path
default to "/sys/fs/bpf".

- Adds new `maps_mut()` API to the BpfManager to allow us to iterate though
and pin all of maps at the same time.

- Adds new pin()/unpin() api to Maps so they
can be generically pinned AFTER load.

- Adds macro for pinning explicit map types in aya.
Convert all explicit map types "inner" field to be
pub crate in order to facilitate this.
