runqemu: add QB_ROOTFS_EXTRA_OPT parameter
Content of the optional parameter will be appended to the rootfs-device in the qemu configuration, in case QB_ROOTFS_OPT is not specified. By default this is empty. Example use cases are: Defining 'readonly' when using squashfs, so multiple instances of qemu can share the same base image, something that cannot be done by just specifying 'snapshot'. Defining 'bootindex=0' which helps to get past the EFI shell in ovmf-binary. This also enables the use case of running WIC images with EFI bootloader through the testimage.bbclass.
