Eduard Zingerman a5a7b25d75 bpf: guard BTF_ID_FLAGS(bpf_cgroup_read_xattr) with CONFIG_BPF_LSM 
Function bpf_cgroup_read_xattr is defined in fs/bpf_fs_kfuncs.c,
which is compiled only when CONFIG_BPF_LSM is set. Add CONFIG_BPF_LSM
check to bpf_cgroup_read_xattr spec in common_btf_ids in
kernel/bpf/helpers.c to avoid build failures for configs w/o
CONFIG_BPF_LSM.

Build failure example:

    BTF     .tmp_vmlinux1.btf.o
  btf_encoder__tag_kfunc: failed to find kfunc 'bpf_cgroup_read_xattr' in BTF
  ...
  WARN: resolve_btfids: unresolved symbol bpf_cgroup_read_xattr
  make[2]: *** [scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 255

Fixes: 535b070f4a ("bpf: Introduce bpf_cgroup_read_xattr to read xattr of cgroup's node")
