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.

This package provides the %{mistralrs_flavour} flavour, built with features:
cuda, cudnn, and optionally flash-attn and nccl depending on flavour name.
The binary installs to %{_bindir}/mistralrs-server-%{mistralrs_flavour}.
Use `update-alternatives --config mistralrs-server` to select the default
/usr/bin/mistralrs-server symlink target.
