fix(cli): minikube start --mount --mountsting without write permission

[NsLib]

fix #2661

var mountTemplate = `
sudo mkdir -p {{.Path}} || true;
sudo mount -t 9p -o trans=tcp,port={{.Port}},dfltuid={{.UID}},dfltgid={{.GID}},version={{.Version}},msize={{.Msize}} {{.IP}} {{.Path}};
sudo chmod 775 {{.Path}}`

The last command (sudo chmod 775 {{.Path}}) can be failed silently when we mount /Users into the VM.
