bpf: Replace map types to use &self, remove HashMap::get_mut

The bpf_map_defs are now wrapped with UnsafeCell, which also happens to
provide a cozy way to get a *mut pointer. An UnsafeCell isn't strictly
required as the struct fields are practically opaque to us, but using an
UnsafeCell follows the general best practices against miscompilation and
also prevents some obvious errors.

HashMap::get_mut was removed because the idea is completely unsound.
Previous users should wrap their data with UnsafeCell instead or use
atomics.

Closes: https://github.com/aya-rs/aya/issues/233

bpf: add PerfEventByteArray

Similar to PerfEventArray but allows to output variable length byte
slices
