spec: Add a basic spec and Makefile targets

This adds the srpm and rpm build makefile targets (borrowed from
osbuild), and uses the pyproject rpm macros to support pyproject.toml
The version is hard-coded into the spec so it will need to be changed at
the same time as the version in pyproject.toml

Fixes #44
