RFR[9] JDK-8170523: Some PKCS11 test cases are ignored with security manager

[John Jiang]

Hi,
Some PKCS11 tests call PKCS11Test.getDistro(), which run command "uname 
-v", to determine the OS distro.
But if the tests enable security manager and don't grant appropriate 
file permission, PKCS11Test.getDistro() fails to get the distro.
Then, the associated cases will be ignored since the tests think that 
the OS is not the target.
