Display Debian package version in hypervisor log

During hypervisor boot, disable the banner and nicely display the xen
version as well as the Maintainer address from debian/control.

For this to work the SOURCE_BASE_DIR variable needs to be set by the
build system to the top directory, i.e. where the debian folder is.

Original patch by Bastian Blank <waldi@debian.org>
