selftests/powerpc: Add ptrace setup_core_pattern() null-terminator
- malloc() does not zero the buffer,
- fread() does not null-terminate it's output,
- `cat /proc/sys/kernel/core_pattern | hexdump -C` shows the file is
not inherently null-terminated
So using string operations on the buffer is risky. Explicitly add a null
character to the end to make it safer.
