Abhijit, please help review the changes for

7175845:"jar uf" changes file permissions unexpectedly
7177216: native2ascii changes file permissions of input file

webrev is at
http://cr.openjdk.java.net/~sherman/7175845_7177216/webrev/

Background info:

This is a regression triggered by the fix we put in for #7143606 in
which we switched most
use of File.createTempFile to java.nio version Files.creteTempFile in
j2se repository, aimed
to make sure the temporary files created by jvm for its internal use
have more restrict read/
write permission. Unfortunately it appears the changes made in jar and
native2ascii tools
are inappropriate and triggered regression. The fix here is to back out
the change we made
in these two tools.
