[libvirt PATCH] tests: Mock virGetUserRuntimeDirectory() for qemuhotplug

[Andrea Bolognani <abologna@xxxxxxxxxx>]

Not mocking this function results in files being created in the
user's home directory when running the test and in the build
failing altogether inside a constrained environment such as the
one used by pbuilder:

  Could not initialize HostdevManager - operation failed: Failed
  to create state dir '/nonexistent/.cache/libvirt/hostdevmgr'
