Note that is doesn't look like it could be a "container specific" thing. In fact, I tried to setup a "traditional" ARM64 chroot, on the x86 host, again using qemu-linux-user and binfmt (basically, how it is described here: https://en.opensuse.org/HCL:Chroot) and I run into the same issue. BTW, adding brogers@suse.com to Cc, as this is about QEMU.
