powerpc: fix syscall tampering when PTRACE_GET_SYSCALL_INFO is in use

When PTRACE_GET_SYSCALL_INFO is in use, CCR is not loaded, so it has
to be loaded explicitly before tampering.

* linux/powerpc/set_error.c (arch_set_error, arch_set_success):
Explicitly load CCR before changing it when PTRACE_GET_SYSCALL_INFO
is in use.
* NEWS: Mention this fix.
