package/odroid-scripts: relax dependencies to include armeb

odroid-scripts are just scripts, so they should also work on a armeb
board.

Besides, odroid-mali selects it, but it only depends on arm-eabihf,
which means armeb is not ruled out.

Fixes unmet dependencies (with BR2_armeb=y):
    warning: (BR2_PACKAGE_ODROID_MALI) selects BR2_PACKAGE_ODROID_SCRIPTS
    which has unmet direct dependencies(BR2_aarch64 || BR2_arm)
