[PATCH v2] automation: upgrade Yocto to scarthgap

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Upgrade Yocto to a newer version. Use ext4 as image format for testing
with QEMU on ARM and ARM64 as the default is WIC and it is not available
for our xen-image-minimal target.

Also update the tar.bz2 filename for the rootfs.

Signed-off-by: Stefano Stabellini <stefano.stabellini@xxxxxxx>

all yocto tests pass:
https://gitlab.com/xen-project/people/sstabellini/xen/-/pipelines/1390081173

Changes in v2:
- s/EXT4/IMAGE_FMT/
- set IMAGE_FMT before the call to project_build
- also update the filename xen-image-minimal-qemuarm.rootfs.tar.bz2
