build(nix): use crane to build packages

this enables faster incremental rebuilds in nix. it also allows us to
add clippy and cargo test checks more easily. aside from that, i have
tried to carry over things that i think are sensible from the previous
`mkDerivation` call.

the `checkPhase` may as well rather be done in a `installCheckPhase` and
we can set `enableParallelBuilding` to speed up the compilation of
`libbcachefs.a`.
