cros_choose_profile: add a board_root flag
This allows us to use setup_board for another directory than /build/${BOARD}.
BUG=chromium:423159
TEST=* ./setup_board --board=gizmo
* ./setup_board --board=gizmo --board_root=/tmp/mysysroot
* diff -r /build/gizmo /tmp/mysysroot are the same except for
* packages/Packages, timestamps, random ids and make.conf.board_setup.
TEST=trybot run on lumpy-incremental, chromiumos-sdk
