powerpc: Remove ancient DEBUG_SIG code
We have some compile-time disabled debug code in signal_xx.c. It's from some ancient time BG, almost certainly part of the original port, given the very similar code on other arches. The show_unhandled_signal logic, added in d0c3d534a438 (2.6.24) is cleaner and prints more useful information, so drop the debug code.
