java: Extract JattachTimeout from JattachException

[Jongy]

This gives JattachTimeout exception name (plus more nice details) to timeout of jattach, to differentiate them from other JattachExceptions.

Here's how it looks:

jattach timed out (timeout was 30 seconds); you can increase it with the --java-jattach-timeout parameter.

In another PR I shall add identification of attach socket missing, which is also a common case.
