Disable unit testing setting up QTcpServer on special Apple interfaces

The iBridge interface is used for the keyboard touch bar, and the Apple
Wireless Direct Link interfaces are used by Apple for various purposes.
Setting up a server on these interfaces does not work.
Only the tst_QTcpServer::linkLocal unit test on macOS is affected by
this change.
