Move platform check into modules
Before, loading a module would be guarded by an optional platform
condition. This made it possible to avoid loading and evaluating a
module if it did not support the host platform.

Unfortunately, this made it impossible to share a single configuration
between GNU/Linux and Darwin hosts, which some wish to do.

This removes the conditional load and instead inserts host platform
assertions in the modules that are platform specific.

Fixes #1906
