The silliness of the second option should be enough to make the choice.
Mentioning in the description, and in an error message at launch time,
that the package doesn’t work without SSE2, should be more than enough.

I have doubts about the existence of such qemu guests that wouldn’t be
KVM-enabled.

In any case, you have the option to disable the testsuite depending on
the contents of /proc/cpuinfo.
