Include diagnostics in archive produced by jpackcore

[keithc-ca]

A new entry in the archive, execution-log.txt mirrors the output produced by running jpackcore, except for the line of the form

VM set to 00007F7BB00131F0

which is produced by native code, and the final line of output

jextract complete.

A sample execution-log.txt follows:
