libpam: Fix runtime providers

The runtime providers were commented out. Removing the comment brings
up a issue with the native renaming which has been workarounded
disabling the runtime recommendation. This is indeed a workaround so a
FIXME comment has been added to remind about it in case we someday
move to native prefix.
