NaCl: Remove nacl_thread.h from NaCl SDK

nacl_thread.h only defines nacl_tls_get() and nacl_tls_init(), which are
not generally useful for application code.  They are only used
internally within libc/libpthread.

This is part of general cleanup to reduce Chromium-side dependencies on
NaCl headers that are not in public directories (src/include/nacl and
src/public).
