KML test macro allows libkml to be older than required

The KML test macro checks the libkml version and even prints the warning message if the version installed is older than required. But the configure system still accepts this library to build with and effectively fails on compilation stage. I think that macro should return negative result if found libkml is older that needed. Attaching the patch to fix it.
