automation: qemu-alpine-arm64: Cleanup and fixes

Perform the following cleanup:
- rename the device tree from virt-gicv3 to virt-gicv2 as the GIC version
  used in this test is v2,
- use fdtput to perform modifications on the dtb,
- use DEBIAN_FRONTEND=noninteractive to prevent interactive prompt being
  stuck waiting for answer other than "yes",
- fix the number of cpus in the device tree because currently we generate
  it with a single cpu and try to run QEMU with two,
- fix the memory size we pass when generating QEMU device tree as it does
  not match the memory size with what we run QEMU.
