flash-wrs: add undocumented support for fake flashing 

If $WRS_FAKE_FLASHER is not empty, no flashing is done but commands
are reported to the user.

If $WRS_KEEP_TEMPORARIES is not empty, all temporary files are
preserved.

I need both features to make the new flashing procedure for the
upcoming 3.4 release.
