fix: point kind/helmfile/helm/k9s/yq bin_dir at /usr/bin

bin_dir was '/usr/bin/<name>', which the download_install_binary role
turns into '/usr/bin/<name>/<name>'. When the binary is already
preinstalled as a file at /usr/bin/<name> (e.g. ubuntu26 base-os
template 144), the role fails with '[Errno 20] Not a directory'.
Point bin_dir at the directory /usr/bin like every other tool.
