You need to tell runqemu to use the file "agl-demo-platform-qemux86-64.ext4".
To do this, check  "runqemu" documentation:

Usage: you can run this script with any valid combination
of the following environment variables (in any order):
  KERNEL - the kernel image file to use
  ROOTFS - the rootfs image file or nfsroot directory to use
  MACHINE - the machine name (optional, autodetected from KERNEL filename if 
unspecified)
  Simplified QEMU command-line options can be passed with:
    nographic - disable video console
    serial - enable a serial console on /dev/ttyS0
    slirp - enable user networking, no root privileges is required
    kvm - enable KVM when running x86/x86_64 (VT-capable CPU required)
    kvm-vhost - enable KVM with vhost when running x86/x86_64 (VT-capable CPU 
required)
    publicvnc - enable a VNC server open to all hosts
    audio - enable audio
  tcpserial=<port> - specify tcp serial port number
  biosdir=<dir> - specify custom bios dir
  biosfilename=<filename> - specify bios filename
  qemuparams=<xyz> - specify custom parameters to QEMU
  bootparams=<xyz> - specify custom kernel parameters during boot
  help: print this text

Examples:
  runqemu qemuarm
  runqemu tmp/deploy/images/qemuarm
  runqemu tmp/deploy/images/qemux86/.qemuboot.conf
  runqemu qemux86-64 core-image-sato ext4
  runqemu qemux86-64 wic-image-minimal wic
  runqemu path/to/bzImage-qemux86.bin path/to/nfsrootdir/ serial
  runqemu qemux86 iso/hddimg/vmdk/qcow2/vdi/ramfs/cpio.gz...
  runqemu qemux86 qemuparams="-m 256"
  runqemu qemux86 bootparams="psplash=false"
  runqemu path/to/<image>-<machine>.vmdk
  runqemu path/to/<image>-<machine>.wic


so you can do
export ROOTFS=./tmp/deploy/images/qemux86-64/agl-demo-platform-qemux86-64.ext4
runqemu qemux86-64 


If unsure, specify KERNEL and MACHINE likewise until it works.
