[PATCH] wic/isoimage-isohybrid: check for grub-mkimage

[Ioan-Adrian Ratiu <adrian.ratiu@ni.com>]

The isohybrid plugin uses grub-mkimage but doesn't make sure it gets built.
Add a check to avoid the following error:

Error: A native program grub-mkimage required to build the image was not found (see details above).

Wic failed to find a recipe to build native grub-mkimage. Please file a bug against wic.
