William Findlay 169478c863 Add support for raw tracepoint and LSM programs
This change adds support for the following program types:

* raw tracepoint
* LSM

Supporting LSM programs involved a necessity of supporting more
load_attrs for the BPF_PROG_LOAD operation, concretely:

* expected_attach_type - for LSM programs, it has always to be set to
  BPF_LSM_MAC
* attach_btf_obj_fd - it's often used to reference the file descriptor of
  program's BTF info, altough in case of LSM programs, it only has to
  contain the value 0, which means the vmlinux object file (usually
  /sys/kernel/btf/vmlinux)
* attach_btf_id - ID of the BTF object, which in case of LSM programs is
  the ID of the function (the LSM hook)

The example of LSM program using that functionality can be found here:
