RFR: 8283315: jrt-fs.jar not always deterministically built

[Andrew Leonard]

JarArchive.gmk uses an un-sorted jar @<file list\>, thus depending on exactly how that list gets ordered by relevant OS querys. Such queries can differ in order on different CPU architectures (Intel vs AMD).

This PR adds a "sort" to the jar @<file list\> contents.
