build-appliance-image: add /lib64 symlink

Add a /lib64 -> /lib symlink in case the build appliance is 64-bit.

Building rust-native requires cargo to be run. The native cargo is linked to
look for /lib64/ld-linux-x86-64.so.2 and can't be run without it. The build
produces the following error, even though that file does exist:

	FileNotFoundError: [Errno 2] No such file or directory: '/home/builder/poky/build/tmp/work/x86_64-linux/rust-native/1.66.1-r0/rust-snapshot/bin/cargo'

Trying to run this binary on its own gives:

	qemux86-64:~/poky/build$ tmp/work/x86_64-linux/rust-native/1.66.1-r0/rust-snapshot/bin/cargo
	-sh: tmp/work/x86_64-linux/rust-native/1.66.1-r0/rust-snapshot/bin/cargo: cannot execute: required file not found
