Fix hugepage bugs in the KVM selftests that specifically affect dirty
logging and demand paging tests. Found while attempting to verify KVM
changes/fixes related to hugepages and dirty logging (patches incoming in
a separate series).
Clean up the perf_test_args util on top of the hugepage fixes to clarify
what "page size" means, and to improve confidence in the code doing what
it thinks it's doing. In a few cases, users of perf_test_args were
duplicating (approximating?) calculations made by perf_test_args, and it
wasn't obvious that both pieces of code were guaranteed to end up with the
same result.
