RFR(XXS): 8140514: [TESTBUG] enable sun/security/pkcs11 tests on Linux/ppc64

[Volker Simonis]

Hi,

can somebody please review the following trivial fix to enable the
pkcs11 tests for linux/ppc64:

http://cr.openjdk.java.net/~simonis/webrevs/2015/8140514/
https://bugs.openjdk.java.net/browse/JDK-8140514

The pkcs11 tests need to load the native library libnss3.so the
location of which is system dependent. Until now, the test didn't
consider Linux/ppc64 systems.

The fix is simple: just add a corresponding map entry which maps the
platform to the correct library path. All the systems I've checked
(various Fedora, OpenSUSE, SLES and RHEL distros) have libnss3.so
under /usr/lib64.

Thank you and best regards,
Volker
