nixos/activation: pass the action as an argument to the pre-switch-checks

Browse source 
This allows for instance to reject switching into a configuration, while
still allowing to reboot into that same configuration.

This can be useful for instance to reject switching to a configuration
with a new systemd major version, but setting that same configuration as
the new boot default with `switch-to-configuration boot` is fine.
