This patch deactivates failing tests that depend on network connectivity
to pass in curl.d and socket.d
It deactivates tests in path.d that assume /root

A thread was started on the ldc forum to pursue the possibility of a
version flag to deactivate tests conditionally. The thread is at
https://forum.dlang.org/post/zmdbdgnzrxyvtpqafvyg@forum.dlang.org
