Subject: bpf selftests and page size

Hi!
Bunch of bpf selftests actually depends of page size and has it
hardcoded to 4K. That causes failures if page shift is configured
to values other than 12. It looks as a known issue since for the
userspace parts sysconf(_SC_PAGE_SIZE) is used, but what would be
the correct way to export it to bpf programs?
