Add bcachefs-tools

[kojq]

This is so bcachefs-tools (and btrfs-progs) can be used in the images (iso), should a user want to use those filesystems.

Build notes (bcachefs-tools):

• bcachefs still needs to be enabled in the linux-desktop kernel.
• need to package the dependency libsodium.
• remember to enable networking for cargo.
• needs to be built with -C default-linker-libraries for the symbol __cpu_model.

# Fixes: ld.lld: error: undefined symbol: __cpu_model
RUSTFLAGS+=" -C default-linker-libraries"; export RUSTFLAGS
