David James dee866c121 Remove --build_root from all scripts except mod_image_for_pyauto.sh.
For all scripts, --build_root defaults to /build and is never used. To
remove option clutter, I've deleted this option.

The only script which still references build_root in src/scripts is
mod_image_for_pyauto.sh, which seems to support it for grabbing pyauto
dependencies from a location other than /build/*. This might conceivably
be useful, so I haven't touched that script.

BUG=chromium-os:27364
TEST=Remote trybot run. git grep for references to build_root.
