Previously, if you were working on a cros_workon package on the host, it
would only get updated once -- after that, the package would never build
again.
With this change, we now rebuild host workon packages any time their
timestamp is modified. This replicates the same feature that we already
have for board packages.
BUG=chromium-os:12771
TEST=Verify that host workon packages are rebuilt when the timestamps change,
and only when the timestamps change.
