[PATCH 3/3] selftests/bpf: Define SYS_PREFIX for powerpc

[Saket Kumar Bhaskar <skb99@xxxxxxxxxxxxx>]

SYS_PREFIX was missing for a powerpc, which made a kprobe test to
sys_prctl fail.

Add missing SYS_PREFIX for powerpc.

Fixes: 7e92e01b7245 ("powerpc: Provide syscall wrapper")
Fixes: 94746890202c ("powerpc: Don't add __powerpc_ prefix to syscall entry points")
