Revert "Revert "Scale timer for emulator""
This reverts commit c58c01b14cd45550991be1624146bc813092d202.
Let's add time scaling back, but keep the default scale to 1. The
emulator behavior should be entirely the same. If a test need to be
speeded up, the scale can then be set for that test only.
BUG=chrome-os-partner:19235
TEST=Pass all tests.
BRANCH=None
