Display the timeout value of `dex2oat`'s watchdog in milliseconds.

The value of this timeout is internally represented in milliseconds
and is set as a duration in milliseconds with `dex2oat`'s option
`--watchdog-timeout`. However, it used to be reported in seconds in
error messages, which would misrepresents small values; change error
reporting to display this value in seconds for clarity.
