tools: bpftool: fix compilation with older headers
Compilation of bpftool on a distro that lacks eBPF support in the installed kernel headers fails with: common.c: In function ‘is_bpffs’: common.c:96:40: error: ‘BPF_FS_MAGIC’ undeclared (first use in this function) return (unsigned long)st_fs.f_type == BPF_FS_MAGIC; ^ Fix this the same way it is already in tools/lib/bpf/libbpf.c and tools/lib/api/fs/fs.c.
