mfgtool-initramfs-image.bbclass: Fix parsing when using a barebox bas…

…ed machine

When building for cfa100xx machines, for meta-fsl-arm-extra, the
parsing is aborted with:

,----
| ERROR: No IMAGE_CMD defined for IMAGE_FSTYPES entry
|     'barebox.mxsboot-sdcard' - possibly invalid type name or missing
|     support class
| ERROR: Failed to parse recipe:
|     .../sources/meta-fsl-arm/recipes-fsl/images/fsl-image-mfgtool-initramfs.bb
`----

This error was caused by the image not providing all the filesystem
types as in fact it generates a Gzipped CPIO filesystem and does not
inherit the default ones.

To solve the error we ought to include the override for 'mxs' SoC
family so the right setting is used as well in this set of SoCs.
