[perl #55504] [BUG] Failing test t/op/spawnw.t

Although I cannot be sure that the issues which were cited in the
original post to this RT have been cleared up, I note that there has
been no follow-up discussion in eight months.

So I'm going to resolve this ticket and encourage any new LANG-related
failures to be reported in new tickets in our Trac system
(https://trac.parrot.org/parrot/newticket).

Thank you very much.
