chore(ci): do not fail on runners which use kvm_intel.

[adelton]

Fixes #312.

It is quite hard to hit an Intel machine in the GitHub Actions hosted runner pool so I admit I did not see this change work.

But given the code as written does not check if the content of the /sys/module/kvm_amd/parameters/nested is 1 or Y anyway and on my local kvm_intel machine with kernel 6.18.7-200.fc43.x86_64 here is a

$ cat /sys/module/kvm_intel/parameters/nested
Y

present, this should not decrease the value of that "check" and it could minimize confusion of people who happen to hit kvm_intel upon their first attempt.
