KVM: selftests: use unified time type for comparison
With test case kvm_page_table_test, start time is acquired with time type CLOCK_MONOTONIC_RAW, however end time in timespec_elapsed() is acquired with time type CLOCK_MONOTONIC. This can cause inaccurate elapsed time calculation due to mixing timebases, e.g. LoongArch in particular will see weirdness. Modify kvm_page_table_test to use unified time type CLOCK_MONOTONIC for start time.
