add rpm make target and fix up spec file

Add a new make target to build an rpm. This uses rpmbuild --build-in-place,
so no SRPM is created.

Also clean up the specfile to remove manually-added Requires: that will
be auto-generated, add a couple new BuildRequires: and use macros for
file locations.
