[libvirt] [PATCH libvirt-glib] Fix generation of docs in a VPATH builder

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The DOC_SOURCE_DIR variable was missing the $(top_srcdir) variable
so it could not find the source files when run from a VPATH build.
Empirically the previous comment saying that $(top_srcdir) was not
needed is wrong.
