RFR 8207351 jextract should generate properties file containing meta info under META-INF

[Sundararajan Athijegannathan]

Hi,

Thanks Henry. I've moved args back to main and passing it to Context 
only when calling collectXYZ methods. Also meta-info writing moved to 
collectJarFile(JarOutputStream, …) as suggested.
