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.
