package/android-tools: fix the select logic

The android-tools Config.in.host has some logic to ensure that at
least one of its sub-options is enabled. However, this logic
incorrectly uses the sub-option names from the *target* android-tools
package, while it should be using the ones from the *host*
android-tools package.

Fixes the following kconfig warning:

  warning: (BR2_PACKAGE_HOST_ANDROID_TOOLS) selects BR2_PACKAGE_ANDROID_TOOLS_ADB which has unmet direct dependencies (BR2_PACKAGE_ANDROID_TOOLS && BR2_USE_MMU)
