tools headers uapi: Sync kvm.h copy

2018-10-08T15:09:14Z

To pick up the changes introduced in: 6fbbde9a1969 ("KVM: x86: Control guest reads of MSR_PLATFORM_INFO") That is not yet used in tools such as 'perf trace'. The type of the change in this file, a simple integer parameter to the KVM_CHECK_EXTENSION ioctl should be easier to implement tho, adding to the libbeauty TODO list.
