NaCl: Update revision in DEPS, r6303 -> r6322

This pulls in the following Native Client changes:

r6304: (mcgrathr) Remove magic to get IRT-compatible linking layout for browser-targetted nexes
r6305: (ncbray) Add a hard timeout for the browser tester to stop runaway tests.
r6306: (mcgrathr) Define private __aeabi_read_tp for IRT
r6307: (mcgrathr) Load IRT for spec2k runs
r6308: (jvoung) Bump toolchain deps. Pull in pdox's windows changes:
r6309: (mcgrathr) Remove -lppapi hack for nacl_irt_test
r6310: (sehr) Make __launchExecutableFromFd take a continuation rather than returning success
r6311: (sehr) Remove possible use-after-free attack from console logging.
r6312: (mseaborn) Cleanup: Remove obsolete reference to SDL from comment in sel_main.c
r6313: (bradnelson) Allow branch to get either native_client (as on the buildbots)
r6314: (jvoung) Fix pnacl glibc builder -- no more platform libs in sdk() after removal of link_segment_gap.o:
r6315: (mseaborn) Cleanup: Fix typo in comment
r6316: (mseaborn) Cleanup: Fix spelling: "seperate" -> "separate"
r6318: (mcgrathr) Clean up buildbot context tests, get browser tests re-enabled on trybots
r6319: (ncbray) Fixed how NaCl's build system used asserts.
r6320: (ncbray) Added a stress test for determining now many nexes can be loaded simultaneously.
r6321: (ncbray) Fixed breakage introduced in r6320.
r6322: (mseaborn) Only set SDKROOT for standalone builds - redo r4926.

Also, disable a thread safety stress test that is known to be flaky on
Windows (run_ppapi_ppb_var_browser_test).
