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.
