build_packages: Add skip_setup_board option.

Builders re-running setup_board in build_packages results in wiping
configs set by setup_board unless set in both build_packages and
setup_board. To simplify APIs for builders, add the option for
setup_board to be skipped all together.

TEST=./build_packages --board eve --skip_setup_board
