makedeb: Extract additional information from spec file
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.
