Document the Chromium for Chromium OS 'local_board'

When building Chromium for Chromium OS for Linux (linux-chromeos) there
is a choice of cros_boards, the local system and the Chromium sysroot.
At the moment linux-chromeos builds with the Chromium sysroot won't
run browser_tests on modern Debian systems due to an old version of
libffi. Since developer testing builds don't need to be protable anyway,
the Chromium sysroot is unnecessary. Document how to use the local
system as a solution to this.
