bpf: powerpc: fix broken uapi for BPF_PROG_TYPE_PERF_EVENT
Now that there are different variants of pt_regs for userspace and
kernel, the uapi for the BPF_PROG_TYPE_PERF_EVENT program type must
be changed by exporting the user_pt_regs structure instead of the
pt_regs structure that is in-kernel only.
Fixes: 002af9391bfb ("powerpc: Split user/kernel definitions of struct pt_regs")
