target/ppc: Better CTRL SPR implementation

The CTRL register is able to write the bit in the RUN field, which gets
reflected into the TS field which is read-only and contains the state of
the RUN field for all threads in the core.

TCG does not implement SMT, so the correct implementation just requires
mirroring the RUN bit into the first bit of the TS field.
