Andrey Ignatov 2c6927dbdc selftests/bpf: Test indirect var_off stack access in unpriv mode
Test that verifier rejects indirect stack access with variable offset in
unprivileged mode and accepts same code in privileged mode.

Since pointer arithmetics is prohibited in unprivileged mode verifier
should reject the program even before it gets to helper call that uses
variable offset, at the time when that variable offset is trying to be
constructed.

Example of output:
  # ./test_verifier
  ...
  #859/u indirect variable-offset stack access, priv vs unpriv OK
  #859/p indirect variable-offset stack access, priv vs unpriv OK
