libadmin: overlap warning in strcpy with gcc9

GCC 9 with --enable-checking produces a new warning/error in
afs_utilAdmin.c associated with a strcpy with the potential of an
overlap.  The index used is signed which triggers the new warning. The
source and target of the strcpy are contained within the same higher
level structure.

Change the variable 'index' from signed to unsigned to resolve the
warning/error. Change the variable 'total' in the same structure to
unsigned to be consistent with it's usage with 'index'.
