[libvirt PATCH] tests: poison $HOME and $XDG_RUNTIME_DIR env variables
To attempt to catch unit tests which accidentally create files in $HOME,
or $XDG_RUNTIME_DIR, poison these env vars by pointing them to
directories which don't exist. This should give easier to debug test
failures. For example:
$ VIR_TEST_DEBUG=1 ./qemuhotplugtest
Could not initialize HostdevManager - operation failed: Failed to create state dir
'/bad-test-used-env-xdg-runtime-dir/libvirt/hostdevmgr'
