package/skopeo: select BR2_PACKAGE_HOST_GO

host-skopeo fail to build, using the commands:

    echo BR2_PACKAGE_HOST_SKOPEO=y >.config
    make olddefconfig
    make host-skopeo

This commit fixes the issue by selecting BR2_PACKAGE_HOST_GO
in the Config.in file.

Fixes:

    make: *** No rule to make target 'host-', needed by '/buildroot/output/build/host-go-1.23.2/.stamp_configured'.  Stop.
