Update the OEM area of Flatcar Container Linux to resolve errors in vmtoolsd.service

Flatcar Container LinuxのOEM領域を更新してvmtoolsd.serviceのエラーを解決する

VMwareのOEM機能が搭載されたFlatcar Container Linuxがv2605.5.0にアップグレードされると、 OEM領域が古いままなためにライブラリのバージョンが一致せず、vmtoolsd.service が起動に失敗する。

# systemctl status vmtoolsd.service
