KVM: selftests: Use u8 instead of uint8_t

Use u8 instead of uint8_t to make the KVM selftests code more concise
and more similar to the kernel (since selftests are primarily developed
by kernel developers).

This commit was generated with the following command:

  git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint8_t/u8/g'

Then by manually adjusting whitespace to make checkpatch.pl happy.

No functional change intended.
