nix: Disable checks and remove crane workaround (#26356)

The checkPhase was failing for me in darwin so I turned it off. I think
eventually we'll want to use a separate derivation for tests (which
crane has a helper for).

Crane also solved our issue with spaces in paths so I bumped the flake
to pick up that fix and removed our workaround: ipetkov/crane#808.

Release Notes:

- N/A
