eliminating deb/rpm dependency on python-rpm

[Matt Domsch]

firmware-tools depends on python-rpm because the rpm.versionCompare()
function is called.  This function is provided under the LGPL v2.1 
by the rpm package in lib/rpmvercmp.c.  We _could_ either duplicate
the C code and add our own python binding to it, or could rewrite it
from scratch in python.  Either way, it would eliminate pulling in
python-rpm and its dependent packages (another few) for what is really
only ~100 lines of C code.
