dir: correct fid type for dtest
The dtest utility has had its fid[] arrays defined as 'long' since the
initial IBM import. Commit
0a98548832472152304410e41306adcc5b91f6a2
'dir: Make test utility build again' converted some - but not all - the
fid arrays to afs_int32.
Allow dtest to operate correctly by converting the rest of the fid
arrays to afs_int32.
