Check each potential JRE location only once

i.e., after recent "fdo#83753: consider JAVA_HOME and PATH when selecting JRE"
fix, if jfw_findAndSelectJRE found no suitable JRE in
jfw_plugin_getJavaInfoFromJavaHome or jfw_plugin_getJavaInfosFromPath, do not
re-check those locations in jfw_plugin_getAllJavaInfos.
