[PATCH v2 1/2] extract setting of wt_status.commitable flag out of wt_status_print_updated()

[Tay Ray Chuan <rctay89@gmail.com>]

It may not be obvious from its name that wt_status_print_updated() that
it also sets wt_status.commitable, which affects commit functionality.
Extract this out into a separate function for improved clarity, though
at the expense of executing another loop.

Changed since v1
- move call to _mark_committable() to match original control-flow

  Originally, our placement of the call perhaps befitted aesthetics /
  logical grouping. But perhaps it is a better idea to match the original
  control flow to dispel any suspicion that this patch changed behaviour
  unintendedly.
