update linked_list_allocator to 0.10.4

versions <= 0.10.1 were affected by [CVE-2022-36086][].
note that with 0.10.0 a breaking API change was done which changed the
signature of `init`. this can however be avoided simply by casting back
(to avoid a breaking API change in `alloc-cortex-m` by changing the API
here as well - if wished, this should be done as a separate step).

i've also tried to instead switch to the `init_from_slice` API
(introduced in 0.9.1), however I've failed at getting this to compile
due to lifetimes (i'm sure it's somehow possible and i just missed the
obvious...), but that'd anyway have been a breaking change for
`alloc-cortex-m` and, if done, should be done in a separate step (though
it'd definitely clean the API up and make it nicer!).
