til_settings: filter til_settings_as_arg() results

Most of the time if there are undescribed settings in the
settings hierarchy, they're just noise in the serialized as_arg
form.

So change til_settings_as_arg() to always skip undsecribed
entries, and introduce til_settings_as_arg_unfiltered() for any
use cases that actually want everything included.  The unfiltered
variant may just go the way of the dodo if nothing ever makes use
of it.
