RFR(S): 8044419: TEST_BUG: com/sun/jdi/JdbReadTwiceTest.sh fails when run under root

[Mattias Tobiasson]

Hi,
Could I please have a review of this test bug fix.

Test expects some files to be unreadable. That does not work when 
running as root.
The fix is to ignore the parts for unreadable files when running as root.

bug: https://bugs.openjdk.java.net/browse/JDK-8044419
webrev: http://cr.openjdk.java.net/~miauno/8044419/webrev.01

Tested as non-root on all platforms except embedded.
Tested as root on linux.

Thanks,
Mattias
