qtkeychain: Allow building with Qt 5

So far we don't yet need the Qt 5 build for qtkeychain because the two
packages that depend on it are still using Qt 4. However, the next
upstream version of Tomahawk for example already uses Qt 5, so let's
prepare for that.

Tested building against Tomahawk Git master with qt5.qtkeychain.
