task-base: Introduce "vfat" feature to get VFAT support.

* A COMBINED_FEATURE, machine and distro both must have it set for support 
to appear in images.
* For now, deploy just kernel modules. Necessity of dosfstools requires
more thought (and unlikely - vfat cannot be rootfs, so there's nothing to
test/recover as emergency measure, and users can install the tools during
normal operation).
