Initramfs images don't benefit from usual IMAGE_FSTYPES overrides. The
only sane values for them are "cpio.XXX". If IMAGE_FSTYPES is set to
include 'live', building core-image-minimal-initramfs can result in
build error, if the image is built before the kernel. To stop initramfs
images from responding on IMAGE_FSTYPES settings, but still allow
users/developers to override defaults (e.g. to generate "cpio.lzma"
initramfs), introduce INITRAMFS_FSTYPES variable, by default set to
"cpio.gz".
