Subject: bpf: fix build issues on um due to mising bpf_perf_event.h

From: Daniel Borkmann <daniel@iogearbox.net>

commit ab95477e7cb35557ecfc837687007b646bab9a9f upstream.

[ Note, this is a Git cherry-pick of the following commit:

    a23f06f06dbe ("bpf: fix build issues on um due to mising bpf_perf_event.h")

  ... for easier x86 PTI code testing and back-porting. ]

Since c895f6f703ad ("bpf: correct broken uapi for
BPF_PROG_TYPE_PERF_EVENT program type") um (uml) won't build
on i386 or x86_64:

  [...]
    CC      init/main.o
  In file included from ../include/linux/perf_event.h:18:0,
                   from ../include/linux/trace_events.h:10,
                   from ../include/trace/syscall.h:7,
                   from ../include/linux/syscalls.h:82,
                   from ../init/main.c:20:
  ../include/uapi/linux/bpf_perf_event.h:11:32: fatal error:
  asm/bpf_perf_event.h: No such file or directory #include
  <asm/bpf_perf_event.h>
  [...]

Lets add missing bpf_perf_event.h also to um arch. This seems
to be the only one still missing.
