Fix a threading bug in dGPERL_CLOSURE_MARSHAL_ARGS

Previously, dGPERL_CLOSURE_MARSHAL_ARGS used the dSP macro to declare
the stack pointer.  But dSP involves accessing the my_perl pointer which
might be invalid if we've been called from a thread other than the main
one.  To avoid this, manually declare SV **sp first and let
GPERL_CLOSURE_MARSHAL_INIT initialize it after it has set up my_perl via
PERL_SET_CONTEXT.

This fixes the bug with your example program on my system.  Quentin, can you
verify this?
