KVM: selftests: Test max vCPU IDs corner cases
The KVM_CREATE_VCPU ioctl ABI had an implicit integer truncation bug,
allowing 2^32 aliases for a vCPU ID by setting the upper 32 bits of a 64
bit ioctl() argument.
It also allowed excluding a once set boot CPU ID.
Verify this no longer works and gets rejected with an error.
