core-image-minimal-initramfs: set QB_DEFAULT_FSTYPE

Hi,

This is a RFC patch, my concern is that QB_DEFAULT_FSTYPE is only used for qemu boot, it is harmless for non qemu machines, so I assume that it is OK to set it in the image recipe.

There are also other image recipes have the similar issues:
WARNING: meta/recipes-core/images/core-image-minimal-initramfs.bb: QB_DEFAULT_FSTYPE 'ext4' is not in IMAGE_FSTYPES 'cpio.gz'.
WARNING: meta/recipes-extended/images/core-image-testmaster-initramfs.bb: QB_DEFAULT_FSTYPE 'ext4' is not in IMAGE_FSTYPES 'cpio.gz'.
WARNING: meta-selftest/recipes-test/images/wic-image-minimal.bb: QB_DEFAULT_FSTYPE 'ext4' is not in IMAGE_FSTYPES 'wic'.
WARNING: meta/recipes-core/images/core-image-tiny-initramfs.bb: QB_DEFAULT_FSTYPE 'ext4' is not in IMAGE_FSTYPES 'cpio.gz wic'.
WARNING: meta/recipes-core/images/build-appliance-image_15.0.0.bb: QB_DEFAULT_FSTYPE 'ext4' is not in IMAGE_FSTYPES 'vmdk'.

I added the WARNING locally to do the checking. I will fix others if this patch is fine.

BTW, I'm working runqemu testcases (oe-selftest -r runqemu) recently, please feel free to give your comments on what should be tested.

Fixed:
MACHINE = "qemux86"

$ bitbake core-image-minimal-initramfs
$ runqemu qemux86 nographic
[snip]
Exception: Failed to find rootfs: tmp/deploy/images/qemux86/core-image-minimal-initramfs-qemux86-20170224082533*.ext4 or tmp/deploy/images/qemux86/core-image-minimal-initramfs-qemux86*.ext4
[snip]

This is because core-image-minimal-initramfs doesn't generate ext4 image which is the default value or QB_DEFAULT_FSTYPE, it only generates cpio.gz.
