[U-Boot] use CONFIG_CMD_HOST to enable the host command

Rather then building the host command depending on the configured board
(CONFIG_SANDBOX being defined), use the more common way of enabling it
via the board configuration.

Fixes building of the env target for sandbox as config_distro_bootcmd
failed to sanity check the configuration but couldn't find the
pre-conditions for the host command previously.

This fixed the problem building the env target for me. Thanks!

You are adding a new config, so you should add it to Kconfig instead of here.
