KVM: selftests: Add kvm_has_cap() to provide syntactic sugar
Add kvm_has_cap() to wrap kvm_check_cap() and return a bool for the use
cases where the caller only wants check if a capability is supported,
i.e. doesn't care about the value beyond whether or not it's non-zero.
The "check" terminology is somewhat ambiguous as the non-boolean return
suggests that '0' might mean "success", i.e. suggests that the ioctl uses
the 0/-errno pattern. Provide a wrapper instead of trying to find a new
name for the raw helper; the "check" terminology is derived from the name
of the ioctl, so using e.g. "get" isn't a clear win.
