stages/mkfs.fat: pass -I command line option

Browse source 
The option will force `mkfs.fat` to ignore existing partitions on
the target device. The check is done via the corresponding device
node in sysfs, i.e. the contents of the `partition` attribute in
`/sys/dev/block/<major>:<minor>`. In certain situations this info
can be stale. Passing `-I` will work-around these situations.
