pulley: Don't test hexdumps by default (bytecodealliance#9662)

These are brittle tests as we add/remove opcodes so minimize the number
of tests that are doing this. This is already exposed through other
testing like in Cranelift or disas testing, so don't have any
manually-updated tests with hex dumps.
