Fix loading of libresolv when the .so file (not .so.2) isn't installed
glibc is nice to us and provides a #define with the actual name. On most
Linux systems, the .so file is installed only if the glibc-devel package
is installed. For all of us Qt developers, it's installed. But for end
users, it might not be.
