OvmfPkg/CI: copy shell to virtual drive

Place the EFI shell as EFI/BOOT/BOOT{ARCH}.EFI on the virtual drive.
This allows the "run to shell" CI test case to work even in case the
shell is not included in the firmware image.

This is needed because an followup patch will exclude the shell from
secure boot enabled firmware images.
