LogCompilation suggestion: output system locale

[Chris Newland]

Hi,

It would be useful for JITWatch to know the system locale when the HotSpot
log was output in order to parse some of the numeric values (stamp
attribute etc.).

Would you consider this patch to output the locale inside the <vm_version>
log header tag?

Kind regards,

Chris
