8294993: LingeredApp test update

[kevinjwalls]

There are a few changes we can make to better understand the LingeredApp test when it goes wrong:

startAppExactJvmOpts() should not try and call finishApp unless the process isAlive, that just creates a misleading exception.

waitAppReady() is really waitAppReadyOrCrashed(), and should not timeout immediately after the 1 second sleep, or we lose a second of our timeout value (not critical with a long timeout, but seems more honest).

Show how long we waited when startup/crashing times out.

Show how long a good startup takes, so we have a basic for comparison when it fails.

Show if there are hs_err/core/mdmp files in the working directory after startup/crash attempt.

Also, in open/test/lib/jdk/test/lib/util/CoreUtils.java:

"Move core file" often seems unnecessary, core/mdmp usually being created in the current directory. But getCoreFileLocation() performs Files.move() which takes enough time to not be a no-op.
