nixos/filesystems: Make most simple filesystems compatible with systemd
This includes disabling some features in the initrd by default, this is
only done when the new initrd is used. Namely, ext and bcache are
disabled by default. bcache gets an own enable option while ext is
detected like any other filesystem.
