Subject: [PATCH] nixos/virtualisation/podman: fix negated logic

- !stdenv.buildPlatform.canExecute stdenv.hostPlatform is incorrect.

- Example: buildPlatform = x86_64, hostPlatform = aarch64, x86_64 cannot
  execute (without emulation) aarch64 so this results in !false, which
  is true. This means that the optional string is inserted and x86_64
  will try to run aarch64 docker.
