FAFT: Change the TIME and TEST_CATEGORY fields of FAFT control files

The TIME field is how long the test runs. The definition:
  SHORT < 15m, MEDIUM < 4 hours, LONG > 4 hour

This CL is to change them to fit this rule. And make the stress tests to
the proper category.

BUG=None
TEST=None, trivial change
