mdadm: Fix building errors

In util.c, there is a building error:
'/md/metadata_version' directive writing 20 bytes into a
region of size between 0 and 255 [-Werror=format-overflow=]

In mapfile.c
It declares the fouth argument as 'int *' in map_update,
but in mdadm.h it's previously declared as an array 'int[4]'
