[PATCH] tests/decode: Convert tests to meson

Hi Paolo, I've used "should_fail: true" because from the docs that
seems like the proper thing, but that produces

28/39 qemu:decodetree / err_width1  EXPECTEDFAIL  0.08s  exit status 1

which isn't nearly so reassuring as OK.  I wonder if it would be better
to add a --test-fail switch to decodetree.py, to invert the exit value?
