Fix OVMF paths in README QEMU examples (#4472) 

All three qemu-system-x86_64 examples in README pointed both -drive
if=pflash entries at the same file (/usr/share/ovmf/x64/OVMF.4m.fd).
OVMF needs CODE for the first pflash and VARS for the second; as
written, EFI NVRAM is not initialized correctly.

The path /usr/share/ovmf/x64/ is also stale - the ovmf package has
been replaced by edk2-ovmf, which installs under /usr/share/edk2/x64/.

Fix both in the three examples (testimage loop section, base Boot ISO
block, espeakup variant).

This will create a *20 GB* `testimage.img` and create a loop device which we can use to format and install to.<br>
`archinstall` is installed and executed in [guided mode](#docs-todo). Once the installation is complete, ~~you can use qemu/kvm to boot the test media.~~<br>
