Change pnacl llvm triple to use nacl instead of linux inside plugin.

Change pnacl llvm triple to use nacl instead of linux (inside plugin).

Inside driver change: http://codereview.chromium.org/7737032/

BUG= http://code.google.com/p/nativeclient/issues/detail?id=1554
TEST= build chrome, host files for "run_pnacl_example_browser_test" and "run_pnacl_bad_browser_test" from a nacl repo (since there is no pnacl toolchain downloaded in chrome repo) and load the test.
