powerpc, hw_breakpoint: Cooperate better with other single-steppers
The code we had to clear the MSR_SE bit was not doing anything because the caller (ultimately single_step_exception() in traps.c) had already cleared. Instead of trying to leave MSR_SE set if the TIF_SINGLESTEP flag is set (which indicates that the process is being single-stepped by ptrace), we instead return NOTIFY_DONE in that case, which means the caller will generate a SIGTRAP for the process.
