mfgtool-initramfs-image: Fix override of IMAGE_FSTYPES

The fix to allow the user to override the IMAGE_FSTYPES setting for
mfgtool-initramfs-image [1] does break the default behavior by turning
the setting into a no-op:

```
# $IMAGE_FSTYPES [6 operations]
#   set? /.../sources/meta-freescale/conf/machine/include/imx-base.inc:463
#     "${SOC_DEFAULT_IMAGE_FSTYPES}"
#   set /.../sources/poky/meta/conf/documentation.conf:214
#     [doc] "Formats of root filesystem images that you want to have created."
#   set? /.../sources/poky/meta/conf/bitbake.conf:832
#     "tar.gz"
#   set? /.../sources/meta-freescale/classes/mfgtool-initramfs-image.bbclass:16
#     "cpio.zst.u-boot"
#   override[mxs-generic-bsp]:set? /.../sources/meta-freescale/classes/mfgtool-initramfs-image.bbclass:17
#     "cpio.gz.u-boot"
# pre-expansion value:
#     "${SOC_DEFAULT_IMAGE_FSTYPES}"
IMAGE_FSTYPES="wic.bmap wic.gz"
```

The layer uses an extra variable SOC_DEFAULT_IMAGE_FSTYPES to override
IMAGE_FSTYPES [2], so use it here.
