selftests/bpf: correct CONFIG_PPC64 macro name in comment

A comment in tools/testing/selftests/bpf/progs/test_fill_link_info.c
incorrectly refers to CONFIG_PPC6 instead of CONFIG_PPC64. Correct it.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
