control: Make more packages Linux-only

Most of the architecture-specific packages are already
linux-any, but a few are not. Since the corresponding
features have been explicitly disabled on non-Linux,
update them accordingly.

As a side effect, the runtime dependencies that were
declared as Linux-only no longer need to be handled
in a special way.
