makedeb: Extract additional information from spec file

The Python RPM library doesn't give us
all the information we need from a spec file, such as
the list of file contents, so we must read these directly
from the spec file.    Don't really want to write a full
spec file parser, but this may be necessary to deal with
conditionals in more complex files.

configure: Include the SRPMS repository in the buildroot

With this change, to build a package we just need to do:

   sudo pbuilder --login --configfile pbuilder/pbuilderrc-raring-amd64
   dpkg-source -x /local/scratch/euanh/debbuild/SRPMS/<pkg>
   apt-get build-dep <pkg>
   cd <pkg>-<version>
   dpkg-buildpackage
makedeb: fill in _libdir and _includedir
