[CELL] spufs: fix decr_status meanings

The decr_status in the LSCSA is confusedly used as two meanings:
 * SPU decrementer was running
 * SPU decrementer was wrapped as a result of adjust
and the code to set decr_status is missing.

This patch fixes these problems by using the decr_status argument as a
set of flags. This requires a rebuild of the shipped spu_restore code.
