Use GYP to build nacl_irt

Converts Chrome from using scons to using GYP when building nacl_irt.
This change causes chrome to use GYP based components for untrusted
code. As a benifit, GYP will no longer need to run and scrape scons
output to determine irt dependencies. This also allows us to avoid
invoking scons during the build process.
We roll NaCl deps to get a fix for a simultaneous 32/64 bit build
issue on Windows.

This broke the mac build due to a missing dependency where pthread.h was
unavailable.  This header gets copied to the correct location during the
prep_toolchain action.  I've added the appropriate dependency shown bellow
to the original patch.

This add the addition dependency to ppruntime
