[libvirt] [PATCH v2 2/2] test: qemuhotplugtest mock virFileMakePath

[Christian Ehrhardt]

In certain build environments (e.g. Debian and Ubuntu) $HOME is set
to a non existing path intentionally. That breaks and crashes
qemuhotplugtest by failing the init in virHostdevManagerGetDefault.

Avoid that issue by mocking the virFileMakePath behavior if it is
passed a path that matches $HOME and doesn't exists. That fixes
qemuhotplugtest in Debian/Ubuntu builds of v6.0.0.
