I'm having trouble trying to enable binfmt_misc on Excalibur so I can
run multi-platform docker builds.

I previously had it working on Daedalus by running

# apt install binfmt-support qemu-user-static

# ls /proc/sys/fs/binfmt_misc/
python3.11    qemu-alpha  qemu-armeb  qemu-hexagon  qemu-loongarch64 
qemu-microblaze  qemu-mips64    qemu-mipsel   qemu-mipsn32el  qemu-ppc64 
    qemu-riscv32  qemu-s390x  qemu-sh4eb  qemu-sparc32plus  qemu-xtensa 
   register
qemu-aarch64  qemu-arm    qemu-cris   qemu-hppa     qemu-m68k 
qemu-mips        qemu-mips64el  qemu-mipsn32  qemu-ppc 
qemu-ppc64le  qemu-riscv64  qemu-sh4    qemu-sparc  qemu-sparc64 
qemu-xtensaeb  status

When I try the same on a new Excalibur install I don't see the
binfmt_misc enabled.

# ls /proc/sys/fs/binfmt_misc/
python3.13 register status

Is there anything new required in Excalibur to get this working?
