This fixes the following error:
* check_data_file_clashes: Package taskset wants to install file build_dir/target-powerpc_8548_musl/root-mpc85xx/usr/bin/taskset
But that file is already provided by package * busybox
* opkg_install_cmd: Cannot install package taskset.
Fixes: 3c3d797c4dad ("busybox: enable taskset by default")
