When compiling with clang, it (rightfully) complains about an operator
precedence issue:
abipkgdiff.cc:1646:7: error: operator '?:' has lower precedence than '<<'; '<<' will be evaluated first [-Wparentheses]
? string("Comparison against self SUCCEEDED\n")
^
Fix that by properly placing the parentheses. Also, drop the superfluous
string conversion.
* tools/abipkgdiff.cc (compare_to_self): address clang warning.
