samples/bpf: silence compiler warnings
silence some of the clang compiler warnings like: include/linux/fs.h:2693:9: warning: comparison of unsigned enum expression < 0 is always false arch/x86/include/asm/processor.h:491:30: warning: taking address of packed member 'sp0' of class or structure 'x86_hw_tss' may result in an unaligned pointer value include/linux/cgroup-defs.h:326:16: warning: field 'cgrp' with variable sized type 'struct cgroup' not at the end of a struct or class is a GNU extension since they add too much noise to samples/bpf/ build.
