powerpc/bpf: 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: 002af939 ("powerpc: Split user/kernel definitions of struct pt_regs")
