[POWERPC] ptrace shouldn't touch FP exec mode
One of the gratuitous difference between 32 and 64-bit ptrace is whether you can whack the MSR:FE0 and FE1 bits from ptrace. This patch forbids it unconditionally. In addition, the 64-bit kernels used to return the exception mode in the MSR on reads, but 32-bit kernels didn't. This patch makes it return those bits on both. Finally, since ptrace-ppc32.h and ptrace-ppc64.h are mostly empty now, and since the previous patch made ptrace32.c no longer need the MSR_DEBUGCHANGE definition, we just remove those 2 files and move back the remaining bits to ptrace.c (they were short lived heh ?).
