tools/testing/selftests/ptrace/peeksiginfo.c: add PAGE_SIZE definition
On IBM powerpc where multiple page size value are supported, current ppc64 and ppc64el distro don't define the PAGE_SIZE variable in /usr/include as this is a dynamic value retrieved by the getpagesize() or sysconf() defined in unistd.h. The PAGE_SIZE variable sounds defined when only one value is supported by the kernel. As such, when the PAGE_SIZE definition doesn't exist system should retrieve the dynamic value.
