<Sound Dev> [9] Review Request: 8160217 JavaSound should clean up resources better

[Sergey Bylokhov]

Hello, Audio Guru.

This is a fix for a bug which was found by mach5. A number of tests and 
one place in jdk, incorrectly releases the files streams for the 
temporary files, which caused thousands of files in the tmp folder.

  - The tests are updated, now when the temporary files are created the 
fileoutput streams will be correctly closed. 
File.delete()/File.deleteOnExit() were replaced by Files.delete() which 
will throw an exception if file cannot be removed.
  - The code in ModelByteBuffer.java was updated to close the stream 
from which we read the data.

No regressions were found by jtreg/jck tests.
