bpf, samples: Add -fno-asynchronous-unwind-tables to BPF Clang invocation

The samples/bpf Makefile currently compiles BPF files in a way that will
produce an .eh_frame section, which will in turn confuse libbpf and produce
errors when loading BPF programs, like:

  libbpf: elf: skipping unrecognized data section(32) .eh_frame
  libbpf: elf: skipping relo section(33) .rel.eh_frame for section(32) .eh_frame

Fix this by instruction Clang not to produce this section, as it's useless
for BPF anyway.
