Add a destructor to s2_deframer to release the pipewriter objects owned by
state_out and locktime_out.
opt_writer() allocates these pipewriters dynamically when the corresponding
output pipe is provided. Without a destructor, the objects were leaked when
s2_deframer was destroyed.
Coverity reported CTOR_DTOR_LEAK findings for state_out and locktime_out.
The existing leansdr code was reviewed and confirmed that other users of
opt_writer() explicitly delete the resulting pipewriters in their
destructors, so s2_deframer was missing the corresponding cleanup.
