sota: introduce INITRAMFS_FSTYPES

RAMDISK_EXT and IMAGE_FSTYPES of initramfs-ostree-image should not be
defined separately, because they are representing the same fstype of
a same initramfs image, or else, they turn out to be inconsistent if
the users change one of them.

So we use INITRAMFS_FSTYPES already defined in bitbake.conf, to be able
to set fstype for initramfs. And it should default to ext4.gz.u-boot or
ext4.gz depending on what OSTREE_BOOTLOADER is being set.
