Review Request: JDK-8173096 jmod files are not world-readable

[Mandy Chung]

Updated webrev to put the temporary file in the same containing directory of the target file:
  http://cr.openjdk.java.net/~mchung/jdk9/webrevs/8173096/webrev.01

I want to fix this regression in jdk-9+154.  We can revisit the approach after this fix if necessary.
