build_library: Use original qemu image name in qemu script

The move to symlinking to the qemu-uefi image also resulted in the
qemu-uefi image being referenced in the qemu-bios and qemu-uefi-secure
scripts instead of referencing the image symlinks. Same for the VM name
shown in the qemu window title.
When generating the qemu scripts, use the original qemu image name and
VM name.
