Fix type for abs() calls in misc/bdelta

During the exp-run in bug 208158, it was found that misc/bdeltra gives erro=
rs
with libc++ 3.8.0 [1]:

libbdelta.cpp:207:13: error: call to 'abs' is ambiguous
        if (abs(lastf1Place-h->hash_items[checkMatches[i]].loc) <
            ^~~

This is because abs() is being called with unsigned arguments.  Fix this by
casting the arguments to the appropriate signed type.
