Subject: uri: Mock domcaps returning NO_SUPPORT

With libvirt 9.8.0, the test driver now has a stub getDomainCapabilities
implementation. But we still have some code that needs to handle
a driver with missing domcaps.

Make our magicuri mock return NO_SUPPORT for domcaps, when the URI
doesn't have any domcaps XML passed in. This is enough for our test
purposes.
