selftests/bpf: Add tests for the arena offset of globals

Add tests for the new libbpf globals arena offset logic. The
tests cover the case of globals being as large as the arena
itself, and being smaller than the arena. In that case, the
data is placed at the end of the arena, and the beginning
of the arena is free.
