rpm: Slightly change the way python-rpm is constructed

If python support is enabled we want to make sure that the RPM python support
is packaged properly.

Move the components into the site-packages directory, move the .la files to a
new -dev package.

Add "rpm" as a dependency of python-rpm, otherwise rpm and the associated
libraries won't be available.

Fixup python wrapper to handle automatic relocation, as supported by the
vendor WINDRIVER configuration.  (Based on a patch from Paul Eggleton)

+python/rpmmodules.c: Change the way the python module loads the RPM config
+
+In order to support the RPM_VENDOR_WINDRIVER enhancement of dynamic
+runtime relocation paths, we need to call rpmcliInit instead of 
+rpmReadConfigFiles.  The rpmcliInit will end up calling rpmReadConfigFiles
+after the necessary relocation processing (if enabled).
+
+Code derived from changes suggested by Paul Eggleton.
