setup_board, update_chroot, dev container: use new bincache mirror

This updates the default settings in build scripts to use
https://mirror.release.flatcar-linux.net/
instead of the google storage bucket if no binhost or FLATCAR_DEV_BUILDS
is specified.

Defaults are updated for
* update_chroot (runs at SDK initialisation time)
* setup_board (creates /boards/[ARCH]/) chroots
* the development container
* set_version
