NaCl: Remove/convert NaClLog() calls in components/nacl/
NaCl: Remove/convert NaClLog() calls in components/nacl/

nacl_log.h conflicts with base/logging.h (and hence with other
Chromium headers) because it #defines LOG_INFO.

This change removes non-error logging calls, following the Chromium
style.  I've converted the remaining calls to use LOG(ERROR).
