refactor(rpm): simplify to single /usr/bin/mistralrs-server binary

Drop the flavour-suffixed binary name, flavour-specific systemd unit
names, and update-alternatives machinery. Install a plain
mistralrs-server binary, a single mistralrs@.service template, and
a default.conf.example. Flavour coexistence was over-engineered for
the target audience.
