fix(rpm): rename sysusers files to match package names

cortex-gateway.conf/cortex-neuron.conf implied a hierarchy or coupling
that doesn't exist — cortex and neuron are independent packages.
Each package's sysusers.d file now matches the package name:
cortex ships cortex.conf, neuron ships neuron.conf. Content is still
identical (both create the cortex system user/group), and filenames
remain distinct so the packages can coinstall.
