[PATCH] tests: Enable virpcimock on macOS

[Roman Bolshakov]

In general, it has little sense to use Linux pci mock on macOS but
virPCIDeviceAddressGetIOMMUGroupNum() is relying on the filesystem
layout mocked by virpcimock. And all tests that rely on correct
execution of virPCIDeviceAddressGetIOMMUGroupNum() fail.

Additionally, missing initialization is added to close() to avoid
invocation of real_close() before it's set up.

The change fixes qemuhotplugtest, qemumemlocktest and qemuxml2xmltest.
