Update GN bootstrap build

Bootstrap didn't work due to recent modifications in base.
Unfortunately some new dependencies are required on OSX
and that required adding generated_build_date.h to be
available separately for the bootstrap process.

Tested on Linux and OSX.

BUG=None
TEST=./tools/gn/bootstrap/bootstrap.py
