[PATCH v2 bpf] selftests/bpf: fix bpf_target_sparc check

[Ilya Leoshkevich <iii@linux.ibm.com>]

bpf_helpers.h fails to compile on sparc: the code should be checking
for defined(bpf_target_sparc), but checks simply for bpf_target_sparc.

Also change #ifdef bpf_target_powerpc to #if defined() for consistency.
