tests/arm64-without-qemu-support: disable binfmt not by uninstalling but by writing to /proc/sys/fs/binfmt_misc/qemu-aarch64

Browse source 
Since 1:7.0+dfsg-3, binfmt.d from systemd is used as preferred
alternative to binfmt-support. And systemd does not provide an official
way to trigger binfmt (de)registration besides a reboot.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1012163

Since we also have binfmt-support installed, systemd and binfmt-support
work in parallel so this test becomes flaky and sometimes removing the
qemu packages would have the desired effect and sometimes not.

To make the test deterministic again, we explicitly disable emulation by
writing a 0 to /proc/sys/fs/binfmt_misc/qemu-aarch64
