Revert "trap_handler: Set status.skip_export when halting a wave"

This reverts commit 4c8a849772.  This
change is required for the runtime to generate reliable core dump files,
but this feature has been disabled for now by
816b46868a.  Until it is needed, revert
the ABI change in the trap handler to maintain compatibility with older
debugger.
