w: fix printf compile warning

Building w on an x86_64 system triggers:
w.c:404:4: warning: format '%zu' expects argument of type 'size_t',
                    but argument 4 has type 'int' [-Wformat]

Since we're comparing UT_NAMESIZE to an int, cast it to that type
(since it can't exceed it) and update the printf.
