Improve output on gradle check timeout

The result ends up being reported as 'null' when this script times out.
The output never directly indicates that a timeout occurred, so this
commit makes the output more explicit.

Also this uses the built-in bash variable `SECONDS` that tracks
elapsed seconds from the start of the script instead of trying to
compute this manually.
