libbpf: Fix powerpc's stack register definition in bpf_tracing.h
retsnoop's build on powerpc (ppc64le) architecture ([0]) failed due to
wrong definition of PT_REGS_SP() macro. Looking at powerpc's
implementation of stack unwinding in perf_callchain_user_64() clearly
shows that stack pointer register is gpr[1].
Fix libbpf's definition of __PT_SP_REG for powerpc to fix all this.
