selftests/bpf: Remove not used headers 



The following three uapi headers:

    tools/arch/arm64/include/uapi/asm/bpf_perf_event.h
    tools/arch/s390/include/uapi/asm/bpf_perf_event.h
    tools/arch/s390/include/uapi/asm/ptrace.h

were introduced in commit 618e165b ("selftests/bpf: sync kernel headers
and introduce arch support in Makefile"), they are not used any more after
commit 720f228e ("bpf: fix broken BPF selftest build"), so remove them.
