Eliminate pre-5.9.x conditional code for PERL_PACK_CAN_BYTEORDER

PERL_PACK_CAN_BYTEORDER has been unconditionally defined for versions 5.9.x
and greater, and undefined for 5.8.x. As we are never going to need to
port changes back to maint-5.8 any more, eliminate all the 5.8.x related code,
and the macro that supports it.
