tests/checkasm: add exclude_guest for non-x86 linux perf

The exclude_guest option only has an effect on x86. Omitting
'exclude_guest' defaults to zero which implies that you can count guest
events should you run one. Some non-x86 kernels just ignore it, while
others (e.g. the Asahi Linux kernels) require the user to explicitly set
the option to 1, i.e. the only behaviour that makes sense when counting
guest events isn't supported.
