7904083: Print fatal error messages to stderr

[sendaoYan]

Hi all,

Currently the fatal error message was print to stderr, shows as below. I think it's bettor to print the fatal error message to stderr.

unset JAVA_HOME ; jtreg -version No java executable at java

unset JAVA_HOME ; jtreg -version > /dev/null #nothing

The >&2 usage for echo both works on linux and cygwin. I do not have other OS system to verify this change, but I think the risk of this change is low.
